  • Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed petitioner constructionDecided for petitioner

    “as adopted by the Board in the Institution Decision. The ’253 patent explicitly defines this term, stating: The term “forward flow” is used herein to define an amount of liquid in the lumen 662 that exits the distal end 664 in a distal direction. Forward flow is defined as greater than 6 microliters of fluid (approximately 1 mm of catheter length of ID 0.071″=5.7 μL). Ex. 1001, 38:18–23 (emphasis added). Moreover, in discussing problems with the prior art systems, the ’253 patent states that “[w]hen positive pressure exists at the distal end of the lumen, liquid from inside the lumen exits out from the distal end of the catheter in a distal direction. This is referred to as forward flow.” Id. at 3:8–11. In the ’253 patent, the patentee acted as its own lexicographer as evidenced by usage of language such as “is used herein to define,” “is defined,” and “is referred to as,” to discuss “forward flow.” We find that the definition of “forward flow” in the ’253 patent specification would provide a person of ordinary skill with “reasonable clarity, deliberateness, and precision” as to the meaning of the term. See Paulsen, 30 F.3d at 1480; see also Ex. 1034 ¶¶ 13–14. Thus, we construe the term, “forward flow,” to mean “an amount of liquid in the lumen that exits the distal end in the distal direction that is greater than 6 microliters.” We disagree with Patent Owner’s contention that our construction imports limitations from a single embodiment into the claims. As explained above, the ’253 patent clearly defines the term “forward flow” and this definition is not limited to a single embodiment. In fact, the ’253 patent indicates that, while “[f]orward flow is defined as greater than 6 microliters of fluid . . . [l]ess forward flow is also included in this definition.” Ex. 1001, 38:21–24. The ’253 patent specifies that “the amount of forward flow can be restricted to no greater than 2 microliters or, in a particularly beneficial embodiment, forward flow is approximately zero microliters.” Id. at 38:24– 29. This language indicates that our construction encompasses multiple embodiments from the ’253 patent. We also disagree with Patent’s Owner’s proposed construction of “forward flow” because it is not supported by the ’253 patent specification. Patent Owner contends that “there is ‘no forward flow’ until the full extent of the distal portion” exits the distal end and thus forward flow is prevented when only less than “the full extent of the distal portion” exits the distal end. PO Resp. 9 (emphasis omitted). To adopt Patent Owner’s proposed construction, we would have to essentially ignore the ’253 patent’s express definition of this term. Further, there is no support in the ’253 patent specification for “full extent” or “fully exiting.” We also agree with Petitioner that Patent Owner’s construction effectively eliminates the concept of preventing forward flow because, as Patent Owner acknowledges, it could allow, for example, 20 milliliters of fluid to exit the catheter, which could displace the thrombus into the patient’s vasculature, a problem that the ’253 patent seeks to avoid.

    “As discussed above, we construe “forward flow” to mean “an amount of liquid in the lumen that exits the distal end in the distal direction that is greater than 6 microliters.” Thus, for the ’011 provisional to provide support for this limitation, the provisional must demonstrate that the inventors had possession of preventing greater than 6 microliters of fluid out of the distal end of the catheter. While Patent Owner points to disclosures from the ’011 provisional application that describe the desire to have “a minimal amount of momentum transfer from the fluid column to the stuck clot to unstick the clot sufficiently” and “[t]he exiting movement of fluid [being] limited to a specific volume and/or pressure and is automatically and precisely controlled” to prevent the “possibility of overshooting,” these disclosures would not convey to one of ordinary skill in the art that the inventors were in possession of a device that limited forward flow to no greater than 6 microliters of fluid. PO Resp. 35 (citing Ex. 1003 ¶¶ 15, 16, 138). Patent Owner also contends that the ’011 provisional application provides “multiple examples of liquid flow exiting the distal end of the catheter such that no forward flow occurs, such as 1 microliter or 0.5 mm of column shift.” PO Resp. 36–37 (citing Ex. 1003 ¶ 91). However, the disclosure cited by Patent Owner provides ranges of liquid flow of “approximately 0.001 ml to approximately 1.0 ml, in particular, approximately 0.1 ml to approximately 0.5 ml” and exemplary length of shift distances of “approximately 0.5 mm to approximately 30 mm, in particular, approximately 0.5 mm to approximately 15 mm.” Ex. 1003 ¶ 91. There is nothing in the ’011 provisional application that specifically directs the person of ordinary skill to the portions of these ranges that fall within the ’253 patent’s definition of “forward flow” (i.e., no greater than 6 microliters of fluid). In fact, the majority of the cited ranges are greater than 6 microliters, going all the way up to 1,000 microliters, such that there would be forward flow in these examples. See Ex. 1034 ¶ 25; Purdue Pharma, 230 F.3d at 1326–27 (“[O]ne cannot disclose a forest in the original application, and then later pick a tree out of the forest and say here is my invention. In order to satisfy the written description requirement, the blaze marks directing the skilled artisan to that tree must be in the originally filed disclosure.”); Fujikawa v. Wattanasin, 93 F.3d 1559, 1571 (Fed. Cir. 1996). Further, we note that the ’253 patent differentiates between embodiments that allow forward flow and embodiments in which no forward flow occurs. See Ex. 1001, 32:58–60, 37:19–22; Pet. Reply 10–11. For example, the ’253 patent describes an embodiment in which the “momentum causes a small amount of fluid to move through the distal portion of the catheter [] and create a small distal movement of the clot.” Ex. 1001, 32:47– 51. This same embodiment is disclosed in the ’011 provisional application. Compare Ex. 1003 ¶ 126 with Ex. 1001, 32:16–60. The ’253 patent describes this disclosure as an “exemplary embodiment” in which the “flow of fluid forward . . . is intentional, which is in contrast to other exemplary embodiments herein where substantially no forward flow occurs.” Ex. 1001, 32:57–60; see also, id. at 37:19–22 (“Turning now to embodiments . . . without the forward flow”).8 The ’011 provisional application does not include the subsequent embodiments from the ’253 patent that are described as being “without the forward flow.” See Ex. 1005 ¶ 68; Ex. 1034 ¶¶ 22–23. This further demonstrates that the ’011 provisional application does not support the limitation of “prevent[ing] forward flow.” We also note that the ’011 provisional application does not contain adequate support for the limitation of “substantially prevent[ing] forward flow” even under Patent Owner’s proposed construction. While the ’011 provisional discloses “controlling the distal movement of the fluid column” (Ex. 1003 ¶¶ 15, 16), this does not support Patent Owner’s assertion that the ’011 provisional teaches that “the distal portion of the fluid column is substantially prevented from fully exiting the distal end.” PO Resp. 35–36. For example, as discussed above, the ’011 provisional application discloses permitting distal flow of up to 1,000 microliters, which would likely exceed the amount that could be characterized as the full distal portion. Ex. 1003 ¶ 91; Ex. 1034 ¶ 25. Thus, we find that the ’011 provisional application does not “clearly allow persons of ordinary skill in the art to recognize that [the inventors] invented what is claimed.” In re Gosteli, 872 F.2d 1008, 1012 (Fed. Cir. 1989); Lockwood v. American Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 8 Patent Owner contends that the statement in the ’253 patent regarding the “exemplary embodiment” of “forward flow” is referring to an embodiment in which the volume of the liquid drawn out from the lumen of the catheter is “approximately 0.2 ml.” PO Resp. 40–41 (citing Ex. 1001, 32:35–36; Ex. 1003 ¶ 126; Ex. 2014 ¶ 99). Even if this is correct, the ’011 provisional application does not include the embodiments that the ’253 patent specifically characterizes as being “without the forward flow.” Pet.

    “Based on the above, we determine that, for prior-art determinations under AIA § 102, “there is no need to evaluate whether any claim of [a reference] patent document is actually entitled to priority or benefit under 35 U.S.C. 119, 120.” MPEP § 2154.01(b) (emphasis added). Rather, under the AIA, a reference patent document need only meet the “ministerial requirements” of §§ 119 and 120, and the provisional or other earlier application(s) to which the reference patent document claims a right of priority must “describe[] the subject matter” relied upon in the reference patent document as prior art. 35 U.S.C. § 102(d)(2). Patent Owner has not contested that Teigen meets the procedural requirements for claiming priority to the ’712 patent or the ’095 PCT application. Teigen also appears to meet the ministerial requirements for claiming priority to the provisional applications because it properly claims the benefit of these applications, the ’095 PCT application was filed co-pending with the provisional applications, and the applications share common inventors.

    “Under 35 U.S.C. § 112(a), enablement is separate and distinct from the written-description requirement. Ariad, 598 F.3d at 1344. “The test of enablement is whether one reasonably skilled in the art could make or use the invention from the disclosures in the patent coupled with information known in the art without undue experimentation.” United States v. Telectronics, Inc., 857 F.2d 778, 785 (Fed. Cir. 1988). “[A] patent specification complies with the statute even if a ‘reasonable’ amount of routine experimentation is required in order to practice a claimed invention.” Enzo Biochem, Inc. v. Calgene, Inc., 188 F.3d 1362, 1371 (Fed. Cir. 1999). Whether undue experimentation is needed is not a single, simple factual determination, but rather is a conclusion reached by weighing many factual considerations. In re Wands, 858 F.2d 731, 737 (Fed. Cir. 1988). These factors, referred to as the Wands factors, include: (1) the quantity of experimentation necessary, (2) the amount of direction or guidance presented, (3) the presence or absence of working examples, (4) the nature of the invention, (5) the state of the prior art, (6) the relative skill of those in the art, (7) the predictability or unpredictability of the art, and (8) the breath of the claims. Wands, 858 F.2d at 737. It is Petitioner’s burden to show by a preponderance of the evidence that the claims of the ’989 patent lack enablement. 35 U.S.C. § 326(e). Petitioner’s evidence and argument does not sufficiently establish that the ’989 patent fails to teach those in the art to make and use the claimed invention without undue experimentation. See PO Resp. 58–66. The Petition does not address the Wands factors sufficiently so as to show that undue experimentation is required to make or use the claimed invention. For example, neither the Petition nor Dr. Pearce sufficiently addresses the state of the prior art or the relative skill of those in the art. See Pet. 64–65; Ex. 1002 ¶¶ 145–152; PO Resp. 62. As Patent Owner argues, this is an “omission[] that [is] particularly fatal” to Petitioner’s enablement argument, because Petitioner argues that mechanical expansion and inflation expansion are incompatible and cannot be combined. PO Resp. 62; see Pet. 30–38, 64. Dr. Grundfest, however, testifies that it was well known to combine mechanical and balloon-based expansion in surgical devices. Ex. 2005 ¶¶ 132–136; PO Resp. 56. During cross-examination, Dr. Pearce testified that he “thought about the state-of-the-art in minimally invasive surgery during the 1990s.” Ex. 2003 18:1–14. Dr. Pearce’s testimony is conclusory and does not sufficiently address whether he considered whether it was well known to combine mechanical expansion and inflation expansion in surgical devices. For another example, relying upon the testimony of Dr. Pearce, the Petition asserts that a redesign of the expansion design disclosed in the ’989 patent “would take a substantial amount of time and cost to achieve.” Pet. 65 (citing Ex. 1002 ¶ 149). Likewise, Dr. Pearce testifies, “[s]uch a redesign would take a substantial amount of time and cost to achieve.” Ex. 1002 ¶ 149. Dr. Pearce, however, does not explain sufficiently why combining mechanical expansion and inflation expansion would require a substantial amount of time and cost. See id. For these reasons, we determine that Petitioner has not met its burden of showing by a preponderance of evidence that claims 1–19 are unpatentable under 35 U.S.C. § 112(a) for lack of enablement.” slip op. at 33

    “Factors that may be considered in determining level of ordinary skill in the art include: (1) the educational level of the inventor; (2) type of problems encountered in the art; (3) prior art solutions to those problems; (4) rapidity with which innovations are made; (5) sophistication of the technology; and (6) educational level of active workers in the field. Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007) (quoting Envtl. Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 696 (Fed. Cir. 1983)). We are not persuaded that Dr. Pearce’s testimony concerning the level of skill in the art is erroneous to the extent it does not explicitly require experience related to devices used for uterine surgical procedures or surgical devices that employ expandable inflation-based and mechanical-based components. Patent Owner’s argument and Dr. Grundfest’s testimony is inconsistent with the ’989 patent, which does not disclose an ablation device or method of using an ablation device that solves problems unique to endometrial ablation or unique to surgical devices that employ expandable inflation-based and mechanical-based components. The ’989 patent does not limit the art to be “the field of minimally invasive surgical and uterine devices” (Ex. 2005 ¶ 60). The ’989 patent states: “The present invention relates generally to the field of apparatuses and methods for ablating or coagulating the interior surfaces of body organs. Specifically, it relates to an apparatus and method for ablating the interior linings of body organs such as the uterus and gallbladder.” Ex. 1001, 1:20–24; see also id. at 2:36–38 (“The present invention is an apparatus and method of ablation and/or coagulating tissue, such as that of the uterus or other organ”).” slip op. at 16

    “We agree with Patent Owner (Prelim. Resp. 12) that claim 1, as a whole, is directed to an apparatus that facilitates voice communication and captioned text communication using a relay for hearing-impaired users over one or more communications networks and, under specified circumstances— when captioning has been enabled by the hearing-impaired user and the system determines that an attempted connection has failed—automatically reconnects to a captioning communication service. In other words, the claim is directed to a communication device that automatically reconnects to a captioning communication service following an unwanted interruption to the 12 captioning communication service in certain circumstances. See Ex. 1001, 1:13–16 (describing the field of the disclosure as relating to a communication device that automatically reconnects to the captioning communication service “following an unwanted interruption to the captioning communication session”). We determine that claim 1 as a whole is not directed to redialing a telephone as “callers have performed for as long as there have been telephones.” See Pet. 20. Moreover, the claim is directed to an apparatus having communication elements and a processor, and requires two connections and captioning, which, taken as a whole, distinguish claim 1 from a conventional telephone and further supports our determination that the claim merely involves, but is not directed to, the concept of reconnection or redialing. Moreover, looking at the elements individually, claim 1 requires communication elements coupled with a processor configured to able to connect a communication device and connect with a captioning session over two connections. Claim 1 recites a function—“automatically connect with the captioning communication service through a second connection to establish a captioning communication session during the voice communication session responsive to a determination that an attempted connection to the captioning communication service failed during a time in which a caption select option has been enabled by the hearing-impaired user, wherein the attempted automatic connection through the second connection is not made during a time in which the caption select option has been 13 disabled by the hearing-impaired user”—which requires more than “redialing” a telephone. See Prelim. Resp. 11–12. Specifically, the claimed apparatus only performs the “automatically connect” function if three conditions are met: (i) responsive to a determination that an attempted connection to the captioning communication service failed (ii) during a time in which a caption select option has been enabled by the hearing-impaired user, and (iii) “the attempted automatic connection through the second connection is not made during a time in which the caption select option has been disabled by the hearing-impaired user.”” slip op. at 12

    “excerpts from Parker as purportedly describing aspects of the automatically reconnect limitation. Id. at 40–42. Petitioner does not assert that either the Ultratec User Guide or Parker alone would have conveyed to one of ordinary skill in the art the automatically connect function with the three conditional limitations (id.), nor is such an assertion required under 35 U.S.C. § 103. Petitioner is required under 35 U.S.C. § 103, however, to explain how the combination of the references would have conveyed to one of ordinary skill 25 in the art the recited automatically connect function with its three conditional limitations. Petitioner has not provided such an explanation, much less adequate analysis by Mr. Zatkovich or factual support as to how one of ordinary skill in the art would understand the separate disclosures of the references to teach the automatically connect limitations. Specifically absent from the Petition is any discussion as to how Petitioner’s combination of references would have conveyed to one of ordinary skill in the art the limitations of automatically connecting under the required conditions—the failed attempt limitation, the when-enabled limitation, and the when-not-disabled limitation. Petitioner’s combination relies on Parker’s reconnection function to establish a lost persistent connection, but Parker’s reconnection function does not do so conditionally, much less under the specific conditions required by claim 1. Petitioner does not explain how the combination of Parker’s unconditional reconnection function would be understood by one of ordinary skill in the art to retry conditionally based on whether the Ultratec User Guide’s caption button was enabling captioning and had not been disabled by the caption telephone user. Furthermore, Petitioner contends that “adding an auto-retry and/or auto-reconnect feature as in Parker to a captioned telephone device as disclosed in [the Ultratec User Guide and Engelke] would amount to simply adding a known technique to a known system, wherein the technique operates in the same way as it was already known to operate and dos not have any unpredictable result.” Pet. 34. As such, Petitioner’s combination 26 expressly relies on Parker’s auto-retry and/or auto-reconnect feature “as in Parker,” which is an unconditional retry in the event of a lost connection. In sum, neither reference by itself describes the automatically reconnect limitation and Petitioner fails to articulate how one of ordinary skill in the art would have understood the claimed automatic reconnect in view of the cited disparate disclosures from the references. “[A] patent composed of several elements is not proved obvious merely by demonstrating that each of its elements was, independently, known in the prior art.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). Petitioner asserts in a conclusory manner that the combination of a teaching of a button to enable or disable captioning with a teaching of automatic reconnection unrelated to whether captioning is enabled or disabled would have conveyed to one of ordinary skill in the art the automatic reconnection limitation. Petitioner fails to provide adequate explanation or factual support. This flaw of the Petition is particularly problematic when the threshold for institution is “more likely than not,” as here, rather than the threshold of “a reasonable likelihood” required to institute an inter partes review.

    “that requires construction beyond what was done at the time of institution. Specifically, substitute claim 6 replaces the term “placing” with the new term “hanging.” We see no reason to interpret “hanging” apart from its plain and ordinary meaning. Thus, consistent with its dictionary definition, we construe “hanging” as “to fasten to some elevated point without support from below.” Merriam-Webster’s Collegiate Dictionary, 10th ed.

The substitute claims also use the transitional phrase “consisting essentially of,” which Shinn Fu argues should be construed presumptively as equivalent to “comprising.” Opp. 3–4 (citing Manual of Patent Examining Procedure § 2111.03). Tire Hanger argues for a narrower construction because, in its view, any additional steps would “materially change the basic and novel characteristics of the claimed method,” pointing to column 1, lines 26–59, of the ’897 patent. Reply 3 (citing Ex. 1002). We are not persuaded that a skilled artisan would view adding a simple extra step, such as raising the wheel to trip a safety latch while removing the wheel from the support arm (see, e.g., Ex. 1012, Fig. 2, 2:61–70), as materially changing the basic objective of the claimed invention in terms of being “easily accessible within the work space,” “remain[ing] out of the way,” and “not requir[ing] workers to bend over,” as made clear in the specification. Ex. 1002, 1:54–59.

  • ScopeMotion to amend, grantedDecided for patent owner

    “enlarge the scope of the claims of the patent or introduce new matter.” Shinn Fu argues that claim 9, which Tire Hanger proposes as a substitute for original claim 4, impermissibly enlarges claim scope by deleting the requirement that the individual “does not have to bend significantly at the waist to guide the wheel over the hanger.” That omission, in Shinn Fu’s view, makes claim 9 broader, not narrower, because it infers that an individual may indeed be bending over while handling the wheel on the support arm. Id. at 21–22. We disagree. Claim 9 depends from substitute claim 6, which recites that, when the vehicle is elevated, “the human can remove the wheel without bending over,” and when the wheel is on the support arm, the wheel can be removed “without the human bending over.” Thus, as a matter of dependency, claim 9 incorporates the limitations from claim 6 that entail handling the wheel on the support arm “without the human bending over.” That an amendment simply removes a limitation from a dependent claim and adds it 11 Shinn Fu also argues that the Motion to Amend should be denied because Tire Hanger failed to comply with its obligation of first “conferring with the Board” before filing the Motion, as required by 37 C.F.R. § 42.121(a). Opp. 2. We are not inclined to deny the Motion to Amend on this procedural ground. Before filing the Motion, Tire Hanger’s legal representative contacted the Board to seek clarification on whether a conference call was necessary and was advised it was not. Ex. 2008 ¶¶ 1–4. As such, we are satisfied that Tire Hanger fulfilled its obligation of conferring with the Board. to the claim from which it depends does not mean that the amendment has broadened the scope of the dependent claim from which the limitation has been removed.

According to Shinn Fu, the specification only refers to a “worker” performing the steps of removing and replacing the vehicle’s wheel, not a “human.” Id. In Shinn Fu’s view, by using the term “human,” rather than “worker,” in the substitute claims, Tire Hanger has broadened the claims to include “such embodiments or species as newborns, toddlers, children, disabled people, and decrepit people,” for which the specification purportedly lacks written description support. Id. We construe claims based on a reasonable interpretation in light of the specification and prosecution history. Shinn Fu’s proposed construction is unreasonable. The specification of the ’897 patent speaks expressly in terms of “individuals in handling tire/wheel assemblies when mounting and removing them from vehicles.” Ex. 1002, 1:41–43 (emphasis added). Likewise, the original claims refer to “a person” and “an individual” in describing removal of the wheel from the vehicle. Id. at 8:24–30.

    “Komorita, on the other hand, presents a different picture because it clearly discloses what is called a “tire hanger” on an automotive lift. Ex. 1004, Abstract, Fig. 29. Even so, Tire Hanger asserts that the claimed method is patentable over Komorita because Komorita “merely teaches placing a wheel in a cradle” for holding the wheel from below, not “hanging the wheel on the support arm” or “guiding a hole in the wheel over the support arm,” as required by substitute claim 6. Mot. 13–14; Reply 9; Tr. 30–31. Thus, the question arises as to whether “hanging” a wheel on “a support arm,” per claim 6, is patentably distinct from supporting the wheel from below in a cradle, per Komorita. We conclude it is. To begin, we previously construed the term “hanging” to mean “to attach or place something so that it is held up without support from below.” See section III.A.2 above. Notwithstanding that Komorita is labeled as a “tire hanger,” it is clear from Komorita that the structure actually disclosed is not a hanger but a cradle that supports the wheel from below. Ex. 1004 ¶¶ 113, 114, Fig. 29. Thus, given our claim construction, Komorita does not appear to meet the “hanging” limitation of substitute claim 6. Moreover, the ’897 patent expressly distinguishes the claimed invention from cradle-like structures, such as that of Komorita. Notably, the ’897 patent describes various embodiments of hangers, each of which is “adapted to fit inside the rim of the tire/wheel assembly.” Ex. 1002, 6:17–21 (emphasis added). Figure 6 of the ’897 patent depicts one such embodiment with the hanger inside of the tire/wheel assembly. The ’897 patent goes on to state that “other structures may be used” to support a tire/wheel assembly, such as “an arcuate cradle” configured “to receive a tire therein . . . to rest the tire in the cradle.” Id. at 6:22–24 (emphases added). Further, another embodiment of a cradle is described that includes “a plurality of arms . . . adapted to receive and hold a tire therein,” and where the tire “rests in the cradle.” Id. at 6:35–37 (emphases added). A plain reading of the ’897 patent reveals that the hanger structures (id. at 6:15–21) are a separate embodiment from the cradle structures (id. at 6:22–42) because they are disclosed as “other structures” and because their modes of retaining the tire/wheel assembly are different. The hanger structure allows the tire/wheel assembly to hang thereon, and includes a specific structure adapted to fit inside a hole in the tire rim. Id. at 6:15–21. In contrast, the cradle structure receives a tire therein, and comprises a structure adapted to fit around and below the outside of the tire. Id. at 6:22–42. As such, we find that there is a structural distinction between hangers and cradles. Although the ’897 patent discloses both hangers and cradles, proposed” slip op. at 22

    “We are not persuaded by Patent Owner’s evidence that the Australian provisional applications conveyed to a person of ordinary skill in the art a summation algorithm or a summer and equivalents thereof. The preponderance of the evidence is that the cited disclosures from the Australian provisional applications are insufficient for this purpose.” slip op. at 15

    “In addition, we do not find credible Dr. DiEuliis’s testimony that the text in Figure 2B, which states “registration no. generated from user details added to serial no. is encrypted and re-arranged,” describes the addition of two numbers (registration no. and serial no.). There is no previous step in the flowchart depicted in Figure 2B that describes the step of generating the registration number to indicate that the registration number is an input, rather than an output.

Ex. 1007 ¶ 41. with N+M+T digits)”. Ex. 1002, 7:24–25; Pet. 21; Ex. 1007 ¶ 41. In 1992, concatenating three integers to produce the desired result “boils down to two basic approaches: (1) multiplying the first integer and second integer by a power of ten (dependent on the number of digits of the subsequent numbers) and adding the three integers together, or (2) converting the integers to ‘strings,’ concatenating the strings, and converting the result back to an integer.” Ex. 1007 ¶ 42. Using the former approach to produce a number with the combined number of digits as the numbers being combined, which Petitioner argues is the one disclosed in Schull, Dr. Madisetti describes the mathematical operations that can be performed programmatically. The mathematical operation provided by Dr. Madisetti is X*10(M+T) + Y*10T + Z, which uses multiplication and addition. Id. ¶¶ 44; Pet. 21. According to Dr. Madisetti, this approach is a summation algorithm and is “computationally quicker” for the reason that “it is a matter of performing basic calculations and processing smaller numbers, as opposed to converting, combining and reconverting large strings . . . .” Ex. 1007 ¶ 43.” slip op. at 28

  • Obviousness (§103) › Analogous artAnalogous artDecided for petitioner

    “supports Petitioner’s assertion that claim 12 would have been obvious over the combination of Haines and Manduley. As an initial matter, we find Haines and Manduley to be analogous art. The PTO and its reviewing courts have developed and applied a two-step “test” to determine whether a prior art reference is “analogous” art and therefore may be used as evidence with respect to a question of obviousness under § 103. See In re Oetiker, 977 F.2d 1443, 1447 (Fed. Cir. 1992); In re Clay, 966 F.2d 656, 659 (Fed. Cir. 1992); In re Wood, 599 F.2d 1032 (CCPA 1979). Step 1 requires an answer to the following question: “Is the reference within the field of the inventor’s endeavor?” If the answer is “yes,” then the reference is “analogous” and therefore may be used as evidence. If the answer is “no,” then Step 2 requires an answer to the following question: “Is the reference reasonably pertinent to the particular problem the inventor was trying to solve?” If the answer is “yes,” then the reference is analogous and therefore may be used as evidence. Haines and Manduley are analogous art because, like the ’216 patent, they relate to systems for remotely permitted use of software on a device. Ex. 1007 ¶ 59. The scope of the ’216 patent is not limited to personal computers, but, rather, any “platform” on which software runs. Ex. 1001, 2:52–55 (“In broad terms, the system according to the invention is designed and adapted to allow digital data or software to run in a use mode on a platform . . . .”), 2:24–30 (“[T]he term ‘platform’ denotes an environment to be associated with a computer device such as a microprocessor or other data processing device which permits execution of the digital data . . . .”). Even if the Haines and Manduley references could be considered in a different field of endeavor than the ’216 patent because their intended use is postage and parcel systems rather than a personal computer, they are analogous art for the additional reason that they relate to the problem of restricting access to software to those who have a right to use it. Ex. 1001, 2:40–44 (“In this specification, ‘use mode’ refers to use of the digital data or software by its execution on a platform so as to fulfill the seller’s/licensor’s obligations in relation to the sale or license of the right to execute the digital data or software in the use mode.”); Ex. 1005, Abstr., 1:41–49 (“only authorized meter reconfigurations can occur”), 11:13–17; Ex. 1006, Abstr, 1:29–32 (“the marketer may wish to charge the customer a separate amount for each software function or each variety of data and the customer may wish to pick and choose among the functions and/or varieties”), 2:31–63.” slip op. at 43
