929 F.3d 1363
Fed. Cir.2019Background
- Infobridge owns U.S. Patent No. 8,917,772 (the ’772 patent), which claims methods essential to the H.265 (HEVC) video coding standard; Samsung petitioned two IPRs challenging the claims.
- The sole contested prior-art reference on appeal is "WD4," a Working Draft of the H.265 standard developed by the Joint Collaborative Team on Video Coding (JCT-VC) and uploaded Oct. 4, 2011.
- Possible dissemination paths for WD4: (1) discussion at JCT-VC meetings (Torino and Geneva), (2) upload to JCT-VC and MPEG websites (navigation required through meeting folders), and (3) an email from author Benjamin Bross to a JCT-VC listserv including a download link.
- The PTAB instituted both IPRs but, in its final written decisions, found WD4 was not publicly accessible before the patent’s critical date and therefore not prior art; it rejected Samsung’s evidence (notably Bross’s testimony) as conclusory.
- Samsung appealed, arguing (1) it has Article III standing based on its economic interest in a patent pool that licenses the H.265 patents, and (2) the Board applied the wrong legal standard to public accessibility (especially as to the listserv email).
- The Federal Circuit held Samsung had standing, affirmed the Board’s conclusions about the JCT-VC and MPEG websites as supported by substantial evidence, but vacated and remanded the Board’s rejection of the listserv evidence because the Board applied an erroneous legal standard regarding accessibility.
Issues
| Issue | Samsung's Argument | Infobridge's Argument | Held |
|---|---|---|---|
| Standing to appeal | Samsung suffers concrete economic injury from pooled-license royalty allocations if the ’772 patent remains valid | Infobridge did not contest but argued generally | Samsung has Article III standing given the patent-pool license mechanics; appeal may proceed |
| Public accessibility — JCT-VC website | WD4 uploaded to JCT-VC site on Oct. 4, 2011; JCT-VC prominence means artisans would check site | WD4 was only reachable through meeting-folder navigation and known mainly to JCT-VC members | PTAB’s finding that WD4 was not publicly accessible via JCT-VC site is supported by substantial evidence (no showing outsiders would reasonably find WD4) |
| Public accessibility — MPEG website | MPEG site also contained WD4 and was analogous to JCT-VC site | Access required logins; structure hindered reasonable discovery | PTAB’s finding that WD4 was not reasonably findable on MPEG site is supported by substantial evidence |
| Public accessibility — JCT-VC listserv email | Bross emailed a download link to a listserv of 254 JCT-VC members and others; accessibility should be judged by whether an ordinarily skilled artisan could locate WD4 with reasonable diligence | The board treated the email as limited distribution and insufficient to show general dissemination | Court held PTAB applied wrong legal standard (focused on actual recipients rather than whether a skilled artisan could access WD4); vacated and remanded for factfinding under correct accessibility test |
