Federal Circuit Upholds Decision Invalidating Chip Patent Claims
By Editorial Team
The Federal Circuit recently affirmed a ruling by a Delaware federal judge that declared a group of patents related to computer chip design invalid under the Alice test. This decision cleared semiconductor manufacturers Siemens and GlobalFoundries of allegations of infringement.
The patents in question were:
- 7,685,545 – Methods and devices for independent evaluation of cell integrity, changes, and origin in chip design for production workflow
- 8,266,571 – Methods and devices for independent evaluation of cell integrity, changes, and origin in chip design for production workflow
The case involved several law firms representing the parties, including Cleary Gottlieb, HSF Kramer, Kirkland & Ellis, Klarquist Sparkman, and Latham & Watkins. The companies involved were Burke Inc., CLS Bank International, and GlobalFoundries.
The Federal Circuit’s decision was a significant development in the realm of intellectual property law, particularly in the semiconductor industry. The ruling has implications for future patent disputes and the application of the Alice test to assess patent validity.
