LEADER TECHNOLOGIES, INC. v. Facebook, Inc.
678 F.3d 1300
Fed. Cir.2012Background
- Leader sued Facebook for infringement of U.S. Patent 7,139,761; dispute centers on on-sale/public-use bars pre-dating Dec 10, 2002; Leader offered Leader2Leader® with Digital Leaderboard® engine for sale/ demonstration before the critical date; jury found the asserted claims invalid under 35 U.S.C. § 102(b); district court denied Leader's post-trial motions; record supports that pre-critical date software embodied the claims; Leader's trial testimony and interrogatory responses were crucial to invalidity finding; appellate review follows Third Circuit standards for JML/new trial and de novo validity questions.
- Leader admitted in interrogatories that Leader2Leader® powered by the Digital Leaderboard® engine embodies the asserted claims; testimony and contemporaneous documents link pre-critical date software to post-critical date embodiments; offers for sale in 2002 described fully developed software consistent with the claimed invention; jury weighed credibility of key witnesses; district court did not abuse discretion in denying a new trial.
- Evidence included co-inventors Lamb and McKibben testimony, internal Leader documents, and the January 2002 Wright Patterson offer describing the same software as the claimed invention; the record shows substantial evidence that pre-critical date Leader2Leader® fell within the asserted claims; credibility findings support the verdict.
- Court applied de novo review to § 102(b) questions with substantial-evidence standard post-verdict; held that the pre-critical date product did embody the claims and the verdict was supported by substantial evidence; affirmed district court's judgment.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether pre-critical date Leader2Leader embodied the claims | Leader asserts no clear evidence the pre-date product fell inside the claims | Facebook contends admissions and pre-date demonstrations prove embodiment | Yes; substantial evidence supports embodiment before the critical date |
| Whether Facebook proved invalidity by clear and convincing evidence | Leader argues lack of direct proof of embodiment before the critical date | Facebook relies on admissions, documents, and testimony linking pre-date product to claims | Yes; record contains sufficient proof of embodiment pre-dating the critical date |
| Whether the district court abused its discretion in denying a new trial | Leader claims great-weight of evidence supports verdict; new trial warranted | Record supports verdict; Leader’s admissions undermine credibility | No; not an abuse of discretion |
| What is the proper standard of review for § 102(b) on-sale/public-use questions | Standard should be de novo with strict scrutiny | Apply substantial-evidence review after jury verdict | De novo review with underlying facts and substantial-evidence standard applied |
