Arendi S.A.R.L. v. Oath Holdings & Google — Federal Circuit Affirms All Four Arendi Patents Are Ineligible Under Section 101

Background

Arendi S.A.R.L., a Luxembourg-based patent assertion entity, filed two related infringement suits in the District of Delaware in 2013—one against Google and one against Oath (formerly Yahoo). Arendi asserted four patents that generally concern a common idea: identifying information in a document (such as a name or phone number) and using that information to search for related data in an external source, like a contact database.

The district court granted judgment on the pleadings under Rule 12(c) for three of the four patents (’54, ’56, and ’93), finding them patent-ineligible under Section 101. The ’43 patent survived the motion to dismiss and proceeded to a jury trial, where the jury found no infringement and that the claims were anticipated and obvious. Arendi appealed all rulings. Google cross-argued that the ’43 patent was also ineligible under Section 101.

The Court’s Holding

The Federal Circuit affirmed across the board, holding that all four Arendi patents claim patent-ineligible subject matter under Section 101. The court applied the two-step Alice/Mayo framework.

At Alice step one, the court found all four patents are directed to the same abstract idea: identifying information in a document and using it to search an external information source. The ’43 patent’s claims—which the district court had initially found non-abstract based on “beneficial coordination” between two programs—were no different. The court explained that “beneficial coordination” does not appear in the claims or specification; the phrase came from a prior Federal Circuit decision addressing obviousness, not eligibility. The claims merely use “computers as tools to carry out an abstract idea, using their ordinary functions without specific hardware or process advances.”

Arendi’s argument that its “input device” limitation (allowing a user to initiate a search with fewer commands) rendered the claims non-abstract also failed. Reducing the number of user steps, the court held, does not make a claim non-abstract when the specification describes the input device generically as “all types of input devices” including buttons, touchscreens, keyboards, and voice commands.

At Alice step two, the court found no inventive concept in any of the four patents. The claim elements—analyzing information, identifying search terms, querying a data source, and using results—are implemented using generic computer components performing conventional functions. Arendi’s purported improvements (“facilitating interaction between programs” and “reducing user steps”) simply restate the abstract idea identified at step one. Under BSG Tech v. Buyseasons, “a claimed invention’s use of the ineligible concept to which it is directed cannot supply the inventive concept.”

Key Takeaways

• Software claims directed to retrieving and acting on document information remain vulnerable under Section 101. Claims that describe identifying data in a document and searching an external source—without specifying a non-conventional technical implementation—are abstract.
• “Beneficial coordination” between programs is not enough. A claim that two programs work together to provide a better user experience does not make the claim non-abstract, particularly when the programs perform only their ordinary functions.
• Reducing user steps does not equal a technological improvement. Making a task require fewer clicks or commands does not transform an abstract method into patent-eligible subject matter unless tied to a specific technical mechanism.
• Decade-long Arendi litigation ends. Arendi had previously litigated these patents against Apple (in a 2016 Federal Circuit decision) and has now lost against both Google and Yahoo/Oath on eligibility grounds.

Why It Matters

This decision reinforces the high bar for software-implemented inventions to survive Section 101 challenges. For companies building features that parse documents for contact information, phone numbers, or other data and then act on that information (a ubiquitous function in email clients, word processors, and mobile operating systems), the ruling confirms that broad patent claims in this space are likely unenforceable. The decision also serves as a cautionary tale for patent assertion entities: even after surviving a motion to dismiss and proceeding to a jury trial, the Federal Circuit can still invalidate claims on Section 101 grounds that were preserved as alternative arguments.
