In Lynk Labs v. Samsung Electronics, the Federal Circuit determined that “a published patent application can be deemed prior art in an IPR as of the application’s filing date.” The Court affirmed the PTAB’s determination that challenged claims of U.S. Patent No. 10,687,400 (the ’400 patent), which relates to light emitting diodes (LEDs), are
In a decision that underscores the importance of prior art in the context of AI patents, the PTAB recently issued a final decision in Tesla, Inc. v. Autonomous Devices, LLC, IPR2023-01173 (PTAB January 3, 2025), invalidating all challenged claims of U.S. Patent Number 11,055,583 (the “’583 patent”). The case provides some insight into how
In ParkerVision, Inc. v. Qualcomm Inc., No. 2022-1755, -2221 (Fed. Cir.

In Virtek Vision Int’l. ULC v. Assembly Guidance Systems, Inc. the Federal Circuit reversed in part the PTAB’s final written decision in an IPR petition filed by Assembly Guidance, on the basis that the petition failed to identify a motivation to combine elements present in the prior art, stating that: “A reason for combining must exist.” Virtek Vision Int’l ULC v. Assembly Guidance Sys., Inc., 97 F.4th 882, 888 (Fed. Cir. 2024). The Court determined that Assembly Guidance had failed to provide any reasoning why one skilled in the art would be motivated to combine the disclosures of the prior art references, and therefore did not show that the challenged claims were unpatentable.Continue Reading Give Me ONE Reason: Federal Circuit Requires At Least One Reason for Motivation to Combine

Artificial Intelligence (AI) typically involves certain common aspects. This includes, for example, training data, AI training algorithm(s) that use the training data to train an AI model, and predictions and/or classifications as output from the trained AI model. Could a person of ordinary skill in the art (e.g., a computer scientist) find it obvious to combine these common aspects to arrive at any given AI-based invention? The Patent Trial and Appeal Board recently answered “no” in its final written decision in Intel Corporation v. Health Discovery Corporation, IPR2021-00552, Paper No. 38 (September 12, 2022).
