Summary
This Federal Circuit opinion affirms a district court's judgment in a patent dispute where a jury found the asserted claims invalid as anticipated and obvious based on prior art. The court holds that substantial circumstantial evidence supported the jury's implicit finding that a firmware upgrade application was in 'public use' under the pre-AIA statutory bars. The decision also interprets inter partes review estoppel under 35 U.S.C. § 315(e)(2), concluding it limits challenges to printed publication and patent grounds rather than barring the introduction of device-based prior art to prove public use or on-sale invalidity. The court further finds no reversible error in the district court's jury instructions or denial of a motion for a new trial.

Questions Presented
- Whether substantial evidence supports the jury's finding that the Firmware Upgrader was in public use.
- Whether the district court's jury instructions on conception, diligence, public use, and on‑sale were legally erroneous.
- Whether IPR estoppel precludes Ingenico from introducing the Firmware Upgrader at trial.
- Whether the denial of a new trial was an abuse of discretion.
Holdings
- The jury's finding is supported by substantial circumstantial evidence; the court affirms.
- The district court's instructions were proper; no error.
- IPR estoppel does not preclude reliance on grounds (public use, on‑sale, known‑or‑used) that could not be raised in an IPR.
- The denial was not an abuse of discretion; the court affirms.
Key quotations
“Thus, there is substantial circumstantial evidence that would allow a reasonable jury to conclude that a user downloaded and actually used the Firmware Upgrader with the DiskOnKey Device.” (7)
“A general jury verdict of invalidity should be upheld if there was sufficient evidence to support any of the alternative theories of invalidity.” (8)
Factual background
The case turned on whether the DiskOnKey System, including a Firmware Upgrader, was in public use before the invention date. Evidence included a 2002 internal email, a press release, a website download page, and a user guide showing the Firmware Upgrader was publicly available and could be downloaded.
Procedural history
The district court entered a jury verdict finding several claims of U.S. Patents 9,059,969 and 9,774,703 invalid as anticipated and obvious, then denied Ingenico's motions for JMOL and a new trial. Ingenico appealed the verdict and the denial of post‑trial motions.
