“For purposes of institution, we find sufficient Dr. Darrell’s testimony that a person of ordinary skill in the art would have been motivated to combine Choe and Workman because Workman discloses predictive models to identify the horizon line (Ex. 1003 ¶ 146), and additionally, because using Workman’s model to identify the horizon line would have been combining known elements (CNNs and annotation for camera calibration) according to known methods to yield predictable results and used known techniques (CNNs) to improve similar devices in the same way. Pet. 48 (citing Ex. 1003 ¶ 150). We find sufficient for institution Dr. Darrell’s testimony that because these models were well known, a person of skill in the art would have had a reasonable expectation of success in combining the teachings of Choe and Workman to achieve the method of claim 1. Id. at 49 (citing Ex. 1003 ¶ 150). We have reviewed Mr. Andrews’s testimony to the contrary (Ex. 2003 ¶¶ 71–80) but, at this stage, do not find it persuasive. For example, to the extent Patent Owner and Mr. Andrews assert that Choe does not identify any “shortcomings” that would motivate a POSITA to look for a better approach like that of Workman (see Prelim. Resp. 29; Ex. 2003 ¶ 74), we note that it is “not necessary to show that a combination is ‘the best option, only that it be a suitable option,’” and “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill,” Intel Corp. v.

Patent Owner disagrees with Petitioner’s definition and asserts that a POSITA “would have a bachelor’s degree in engineering or computer science with one- or two-years training and/or experience in design of software for camera/sensor systems in the automotive industry.” Prelim. Resp. 12 (citing Ex. 2003 (Declaration of Scott Andrews) ¶ 35). We determine that no express finding is necessary, on the present record, and that the level of ordinary skill in the art is reflected by the prior art of record. See Okajima v.

A person with less formal education but more experience, or more formal education but less experience, could also meet the standard. Pet. 19 (citing Ex. 1007 ¶¶ 68–69). Patent Owner provides a different definition: A person of ordinary skill in the art at the time of the inventions in the ‘002 Patent would have had a bachelor’s degree in computer science or a related field, and at least two years of experience working in the field of software systems used in generating and broadcasting multimedia streams. An individual with less technical education but more experience, or vice versa, could also qualify as a person of ordinary skill in the art. Prelim. Resp. 12 (citing Ex. 2006 ¶ 59) (emphasis added).

“There is no dispute that (1) Avellan’s user initiates the request and eventually receives the stream and (2) gateway server 134 receives a request for a media stream for playback on a broadcast channel. See id. at 32–39; Pet. 22. The issue here is whether claim 1 requires that the recited “content provider” originates the request. We agree with Petitioner that claim 1 does not require this. Prelim. Reply 7. Apart from being received from the content provider, claim 1 does not limit the request’s origin in any way. Rather, claim 1 only requires that the request is received from the content provider. Ex. 1001, 14:51–54. Claim 1 recites “comprising” in the preamble of the method (id. at 14:50), which is a encompasses user-originated requests that are received from other entities. With this understanding of the claim, we preliminarily agree with Petitioner that Avellan discloses limitation 1a through its communication path from network 150 to user computers 1041–104n via gateway platforms 1301–130n. Pet. 22. That is, Avellan’s gateway platform 134 receives a request for at least one media stream, and claim 1 does not exclude user-originated requests. See id.

We determine that Petitioner’s arguments made in connection with those limitations are sufficient at this stage and on this record. Pet. 24–32. We agree with Petitioner that Avellan teaches obtaining content from the networks 150 and 152, as recited in 1b; rendering a webpage by a browser at gateway 134, as recited in 1c; generating the screen captures at gateway 134, as recited in 1d; and assembling and providing the media stream when gateway server 134 compresses the image or video format and sends it to the browser 106, as recited in 1e and 1f.

“II. STANDARD OF REVIEW Under 37 C.F.R. § 42.71(c), “[w]hen rehearing a decision on petition, a panel will review the decision for an abuse of discretion.” An abuse of discretion may be determined if a decision is based on an erroneous interpretation of law, if a factual finding is not supported by substantial evidence, or if the decision represents an unreasonable judgment in weighing relevant factors. See Star Fruits S.N.C. v. United States, 393 F.3d 1277, 1281 (Fed. Cir. 2005); Arnold P’ship v. Dudas, 362 F.3d 1338, 1340 (Fed. Cir. 2004); In re Gartside, 203 F.3d 1305, 1315–16 (Fed. Cir. 2000).

“Lastly, Petitioner contends the Decision overlooked or “misapprehended the facts showing that all steered planar array antennas inherently result in radiation patterns having at least one asymmetrical beam.” Req. 13–15. According to Petitioner, Figure 4 of U.S. Patent No. 5,929,823 (Exhibit 2010) and Figure 3 of U.S. Patent No. 6,198,434 (Exhibit 2011), relied upon in Patent Owner’s Preliminary Response as describing remedies for distortion effects due to asymmetrical beams (Prelim. Resp. 47–48), do not eliminate the inherent asymmetry of the main beam. Req. 14. However, our Decision relies on Paragraphs 151 to 156 of Mr. Cosgrove’s testimony (Ex. 2001), which cite additional sections of Exhibits 2010 and 2011, to determine that the steered beams of a planar array are not necessarily asymmetrical. Dec. 21–23 (citing Ex. 2001 ¶¶ 151–156). For example, Mr. Cosgrove addresses the asymmetric bulge shown in Figure 4 of Exhibit 2010 by citing to a description of Figure 6, which describes a lobe symmetry of main lobe 610 that presents a more slender beam mid-section than that of main lobe 410 of Figure 4. Ex. 2001 ¶ 152 (citing Ex. 2010, 7:65–8:6). Mr. Cosgrove also addresses the asymmetric bulge shown in Figure 3 of Exhibit 2011 by citing to a description of Figure 6, which describes main lobe 610 as substantially symmetric, and more suited than lobe 310 of Figure 3 to provide communications within a defined subsection of an area to be served. Ex. 2001 ¶ 156 (citing Ex. 2011, 10:13–16). Accordingly, the Decision did not misapprehend or overlook any arguments or evidence presented by Petitioner. We did not abuse our discretion in determining that the Petitioner did not adequately establish a reasonable likelihood that a steered beam of a planar array is necessarily asymmetrical.” slip op. at 5

“C. Level of Ordinary Skill in the Art Petitioner’s declarant, Dr. Ratner, testifies that a person of ordinary skill in the art at the time of the alleged invention “would have had an undergraduate degree in Computer Science or a related field, such as Electrical Engineering, and two to three years of experience working in the field, or an equivalent level of experience.” Ex. 1005 ¶ 17; Pet. 14. Patent Owner does not challenge this definition or present its own.

“We agree with and adopt Petitioner’s reasoning and determine Rabinovich to be a printed publication. We credit the unrebutted testimony of Dr. Rabinovich regarding the consistency of his professional practice in 1998 for republication of his AT&T technical memoranda on a webpage that he managed on AT&T’s publicly accessible website. Furthermore, we find the December 1998 IEEE article corroborates the public availability of Rabinovich on that website, and would have been a roadmap, for one of ordinary skill in the art of data management and optimized access to data, to be guided to Rabinovich. See Reply 21–22. As Petitioner points out, Patent Owner’s own declarant states that Rabinovich and the December 1988 IEEE article “are ‘similar[]’ in that they both address ‘problems in network connectivity caused by multiple clients accessing servers.’ (Ex. 2006 at 12).” Id. at 20. Additionally, the passage in the December 1998 IEEE article that cites to Rabinovich refers to an algorithm in Rabinovich for optimizing access to data in order to increase performance. Id. at 21. Accordingly, we find that footnote 16 of the IEEE article, which contains the URL to Rabinovich, would have guided one of ordinary skill directly to Rabinovich.

“whether to replicate data object xs. Rabinovich defines cnt(s,xs) as the “total access count for xs,” which is equal to cnt(xs). Ex. 1006, 11. According to Dr. Ratner, “[t]he metric cnt(s,xs) measures the total number of times in that window that replica xs has been served to a client computer.” Ex. 1005 ¶ 253. As Patent Owner points out, Rabinovich teaches replicating/migrating object xs only if the ratio of cnt(s,xs) over aff(xs) is greater than m, and the ratio can be greater than m only if cnt(s,xs) is greater than zero. PO Resp. 19; Ex. 1006, 12, Fig. 4. In view of this, we agree with Patent Owner that if cnt(s,xs) has a value of zero, meaning that object x has not been served to any client computer, then the ratio of cnt(s,xs) to aff(xs) will be zero, i.e., less than m, and Rabinovich will not carry out its replication or migration step. This means that Rabinovich will not replicate or migrate object xs until xs has been accessed by a client computer at least once, such that the access count for xs is greater than zero. In this regard, we agree with Patent Owner that object xs is not “sen[t], from the at least one data storage device to the another data storage device . . . independent of an access of the at least one client computer” because Rabinovich teaches explicitly that object xs is not sent unless there has been at least one access from the client computer.” slip op. at 18

“Electrical Engineering, and two to three years of experience working in the field, or an equivalent level of experience.” Ex. 1005 ¶ 17; Pet. 16. Patent Owner does not challenge this definition or present its own. Accordingly, we credit the testimony of Dr. Ratner regarding the level of ordinary skill in the art, and find that a person of ordinary skill in the art would have had an undergraduate degree in Computer Science or a related field, such as Electrical Engineering, and two to three years of experience working in the field, or an equivalent level of experience. This level of ordinary skill is reflected not only by the information presented by the parties, but also by the prior art of record. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art itself can reflect the appropriate level of ordinary skill in the art).” slip op. at 9

“We agree with and adopt Petitioner’s reasoning and determine Rabinovich to be a printed publication. We credit the unrebutted testimony of Dr. Rabinovich regarding the consistency of his professional practice in 1998 for republication of his AT&T technical memoranda on a webpage that he managed on AT&T’s publicly accessible website. Furthermore, we find the December 1998 IEEE article corroborates the public availability of Rabinovich on that website, and would have been a roadmap, for one of ordinary skill in the art of data management and optimized access to data, to be guided to Rabinovich. See Reply 19–22. As Petitioner points out, Patent Owner’s own declarant states that Rabinovich and the December 1988 IEEE article “are ‘similar[]’ in that they both address ‘problems in network connectivity caused by multiple clients accessing servers.’ (Ex. 2006 at 12).” Id. at 21. Additionally, the passage in the December 1998 IEEE article that cites to Rabinovich refers to an algorithm in Rabinovich for optimizing access to data in order to increase performance. Id. Accordingly, we find that footnote 16 of the IEEE article, which contains the URL to Rabinovich, would have guided one of ordinary skill directly to Rabinovich. We are, therefore, persuaded, that Rabinovich is a printed publication under 35 U.S.C. § 102.” slip op. at 12

“object xs. Rabinovich defines cnt(s,xs) as the “total access count for xs,” which is equal to cnt(xs). Ex. 1006, 11. According to Dr. Ratner, “[t]he metric cnt(s,xs) measures the total number of times in that window that replica xs has been served to a client computer.” Ex. 1005 ¶ 253. As Patent Owner points out, Rabinovich teaches replicating object xs if the ratio of cnt(s,xs) over aff(xs) is greater than m, i.e., a non-zero value. PO Resp. 34; Ex. 1006, 12, Fig. 4. In view of this, we agree with Patent Owner that if cnt(s,xs) has a value of zero, meaning that object x has not been served to any client computer, then the ratio of cnt(s,xs) to aff(xs) will be zero, i.e., less than m, and Rabinovich will not carry out its replication step. This means that Rabinovich will not replicate object xs until xs has been accessed by a client computer at least once, such that the access count for xs is greater than zero. In this regard, we agree with Patent Owner that Rabinovich object xs is not “sen[t], from the at least one data storage device to the another data storage device . . . independently of an access of the at least one client computer” because Rabinovich teaches explicitly that object xs is not sent unless there has been at least one access from the client computer. We are not persuaded by Petitioner’s argument that Rabinovich” slip op. at 18

“pieces” Claim 1 recites “each file including a plurality of individual pieces, the pieces containing parts of the files.” Ex. 1002, 25:67–26:1. The other independent claims recite limitations commensurate in scope. Neither party proposes explicitly a construction of the term “piece.” Petitioner argues that “files are inherently composed of pieces in the form of bits that make up bytes, the bytes themselves being pieces of the file.” Pet. 32. Patent Owner argues that construing “piece” to cover “bits and bytes” of a file “would read out the ‘pieces’ limitation from the claim entirely” (PO Resp. at 29–30) and that “one of ordinary skill in the art would not read the ‘pieces’ limitation of the claim to include bits and bytes” (id. at 30). The claims themselves define “piece” by requiring that a “file” have a “plurality of individual pieces,” but do not establish a lower bound—i.e., a minimum number of bits or bytes—to qualify as a “piece.” Patent Owner identifies no support in the ’680 patent for its contention that “piece” or “pieces” excludes a byte or bytes of a file, relying instead solely on the testimony of Dr. Paul S. Jacobs. Id. (citing Ex. 2006 ¶¶ 38, 39). We are not persuaded by Dr. Jacobs’s conclusory testimony. Because “piece” and “pieces” are limited by the claims only to being a subset of a file and because a byte or collection of bytes of a file is a subset of that file, we are persuaded that the broadest reasonable interpretation of “piece” and “pieces” in light of the Specification of the ’680 patent encompasses a byte or bytes. slip op. at 7
