The United States Court of Appeals for the Federal Circuit has affirmed the decisions of a Delaware federal court, ruling in favor of Google LLC and Oath Holdings Inc. in patent infringement lawsuits filed by Arendi S.A.R.L. The appellate court concurred with the lower court’s determination that the patents in question were invalid, thereby upholding the judgments in favor of the defendants.
Arendi S.A.R.L., a Luxembourg-based entity, had alleged that Google and Oath infringed upon its patents related to data systems. However, the Federal Circuit’s decision reinforces the lower court’s findings that the patents lacked validity, leading to a dismissal of Arendi’s claims.
This ruling is consistent with previous decisions involving Arendi’s patents. In a 2018 case, the Federal Circuit upheld the Patent Trial and Appeal Board’s (PTAB) determination that all claims of Arendi’s patent were unpatentable due to obviousness in light of prior art. The court noted that even if Arendi’s prosecution disclaimer were accepted, the claims would still be unpatentable for obviousness.

The recent affirmation by the Federal Circuit underscores the challenges patent holders may face when asserting claims against major technology companies, particularly when the validity of the patents is called into question. This decision may influence future litigation strategies and patent filings within the tech industry.
