“B. PERSON OF ORDINARY SKILL IN THE ART In determining the level of skill in the art, we consider the type of problems encountered in the art, the prior art solutions to those problems, the rapidity with which innovations are made, the sophistication of the technology, and the educational level of active workers in the field. Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed. Cir. 1986). The level of ordinary skill in the art is “a prism or lens through which . . . the Board views the prior art and claimed invention” to prevent hindsight bias. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 8
- 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. See PO Resp. 10–12 (citing Ex. 2014 ¶¶ 48–51); Pet. Reply 8–9 (citing Ex. 1034 ¶¶ 14–15).” slip op. at 13
- Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner
“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.

- Novelty / Anticipation (§102) › Prior-art status of a reference › Patents / published applications (effective date, provisional support)Reference is prior artDecided for petitioner
“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. Ex. 1007, codes (22), (60), (63), (72); Ex.1008, 2; Ex. 1009, 2; Ex. 2005, codes (22), (30), (72). Patent Owner does not dispute that Teigen meets the “ministerial requirements” of § 119. Because we find that the Dynamic Drinkware analysis does not apply here, we agree with Petitioner and Patent Owner, that we need not reach the issue of whether a claim from Teigen is supported by either Teigen provisional application.

“ordinary skill is inappropriate because it “requires qualifications that exclude even the sole inventor of the ’190 Patent, Dr. Edward Neuwelt.” MTA Opp. 1. According to Petitioner, Dr. Neuwelt is “a neurosurgeon,” not a pediatric oncologist, and lacks the requisite “at least 2 years” experience in platinum-based therapies. Id. (citing Ex. 1003, 18; Ex. 1038, 98:9–17, 100:15–101, 4). We agree with Petitioner. It is well settled that inventors are typically persons skilled in the field of the invention. Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005) (en banc). Petitioner presents persuasive evidence to show that under Patent Owner’s proposed definition of the level of ordinary skill, Dr. Neuwelt, the sole inventor, would not qualify as an ordinarily skilled artisan, because he is not a pediatric oncologist, even though he is considered “one of the world leading experts on this compound [STS] and otoprotection” and “an expert in the area of [STS] as a . . . drug to use in children with medulloblastoma.” Ex. 1038, 98:9–17, 99:17–18, 101:18–102:13.” slip op. at 10

“that “hyperlink” is a well-understood term that the ’022 patent uses in accordance with its ordinary meaning. As explained above, the Microsoft Computer User’s Dictionary makes clear that a hyperlink includes a connection to another element or document. Patent Owner points to no persuasive evidence that the ’022 patent describes a hyperlink as separate from this connection such that the connection can be changed with the hyperlink remaining the same. Indeed, the ’022 patent describes “replac[ing] all links in the translated web page 7 with links that point to the translation manager 4” as part of the translation process. Ex. 1001, 3:37–38. Thus, as described in the patent, changing the connection to point to the translation manager requires a new link. This is consistent with the ordinary meaning of a hyperlink as including a specific connection from one document to another element or document. Our preliminary construction of “hyperlink” included “a link or connection” but did not include a recitation of the element or document linked. To resolve the parties’ dispute, consistent with the ordinary meaning and the specification, we conclude, on the full record before us, that one of ordinary skill in the art at the time of the invention would have understood “hyperlink” to mean “a connection between an element in a hypertext document, such as a word, phrase, symbol, or image, and a different element in the document, another hypertext document, a file, or a script.”” slip op. at 10

Of note, is that this proceeding is not a jury trial and, thus, the risk of prejudice in this forum is less than what may otherwise exist before a jury. Third, we agree with Petitioner that Exhibit 1013 is not hearsay at least under Federal Rule of Evidence 801(d)(2)(B) because the testimony in Dr. Nakhimovsky’s Declaration was submitted by, and on behalf of, Patent Owner to the Patent Office, thus evidencing that Patent Owner manifested a belief that the statements contained therein were true.

- Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateUnpatentable
“Patent Owner’s first argument is contrary to our constructions of the term “hyperlink” and the phrase “said hyperlink.” As reflected in our construction, “said hyperlink” in each of independent claims 1, 17, and 26, refers back to the original recitation of “one or more hyperlinks” in the original (untranslated) electronic communication. The portion of the specification relied upon by Patent Owner does not disclose providing translation of said further electronic communications when the original one or more hyperlink is activated. Rather, this disclosure indicates that the translation manager may replace all of the links (i.e., hyperlinks) in the translated web page with links that point to the translation manager. These replaced links are in the translated electronic communication (e.g., web page 7), and not in the original untranslated electronic communication (e.g., web page 2). Thus, this disclosure does not reasonably convey to one of ordinary skill in the art that the inventors had possession of a translation manager that provides translation of further electronic communications when the one or more hyperlinks in the original untranslated electronic communication is activated (i.e., one or more hyperlinks with unmodified destination addresses).
