RulingsFinal written decision- Skill levelSkill level petitioner adoptedDecided for petitioner
“ordinary skill in the art, with respect to and at the time of the’502 patent, would have the following qualifications: “a medical physicist with a Ph.D. (or similar advanced degree) in physics, medical physics, or a related field, and two or more years of experience in radiation oncology physics and image processing/computer programming related to radiation oncology applications.” Ex. 1202 ¶ 13. Dr. Hashemi, Patent Owner’s expert, essentially agrees, with the only major differences to the above being that an M.S. is acceptable in lieu of a Ph.D., and that three years of experience is preferred. Ex. 2080 ¶ 17. Nominally, we accept Petitioner’s proffered level because it is based on Dr. Balter’s more complete explanation. We note, however, that neither party has explained substantively any significance that the difference in the proffered levels of ordinary skill in the art would play in the obviousness analysis. See Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966); Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (“[T]he level of skill in the art is a prism or lens through which a judge, jury, or the Board views the prior art and the claimed invention.”); Ryko Mfg. Co. v. Nu- Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991) (“The importance of resolving the level of ordinary skill in the art lies in the necessity of maintaining objectivity in the obviousness inquiry.”). To that end, we note that the prior art itself often reflects an appropriate skill level. See Okajima, 261 F.3d at 1355.” slip op. at 12
- Disclosure Requirements (§112) › Written description (Ariad)Written description adequateDecided for patent owner
“Owner that the ’590 Application provides sufficient written description support for “controlling [said path of / a radiation therapy treatment plan involving] said radiation source based on said image.” In particular, we credit the testimony of Dr. Hashemi that a person of ordinary skill in the art would have understood from the ’590 Application that components of the disclosed system were computer-controlled based upon, e.g., the depiction of an Elekta SL-20 in Figure 3 of the ’590 Application and from the depiction of an electronic portal imaging device. (Ex. 2080 ¶¶ 109–116, 125–132). Petitioner’s arguments are not persuasive because, even assuming that controlling the source path and controlling a radiation therapy treatment plan are “an entirely different class of control step” from controlling patient position (Pet. Reply 8–9), Petitioner has not explained why the portions of the ’590 Application relied upon by Patent Owner do not disclose controlling the source path or controlling a radiation therapy treatment plan.” slip op. at 19

“[t]he content and nature of the printed publication, as well as the circumstances surrounding its publication” (Katz, 687 F.2d at 455), we are not persuaded that Petitioner has met its burden of persuasion by showing sufficiently that the portions of Jaffray 1999 SPIE and Jaffray 1999 JRO on which it relies are the work “others.” Unlike in Katz, where the question was “the sufficiency of applicant’s showing to establish that the subject disclosure was his original work, and his alone” (687 F.2d at 455), the question before us is the sufficiency of Petitioner’s showing to establish that the subject disclosure was the work of the non-inventor coauthors of Jaffray 13 Both the burden of production and the burden of persuasion. 14 At oral argument, counsel for Petitioner indicated that, in his view, it does not matter who has the burden. Tr. 20:9, 20:16–17. 1999 SPIE and Jaffray 1999 JRO. See Dynamic Drinkware, 800 F.3d at 1378 (“In an inter partes review, the burden of persuasion is on the petitioner to prove ‘unpatentability by a preponderance of the evidence,’ 35 U.S.C. § 316(e), and that burden never shifts to the patentee.”); In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1373 (Fed. Cir. 2016) (“In the context of the present case, however, the notion of burden-shifting is inapposite because the patentee’s position is that the patent challenger failed to meet its burden of proving obviousness.”); see also Duncan Parking Techs., Inc. v.
