EcoFactor, Inc. v. Google LLC

Background

EcoFactor sued Google for allegedly infringing U.S. Patent No. 11,835,394, which concerns smart thermostat and heating, ventilation, and air-conditioning technologies. The Court had previously dismissed EcoFactor’s complaint after finding that the asserted patent claims were directed to an abstract idea and lacked an inventive concept sufficient for patent eligibility. The Court allowed EcoFactor one opportunity to amend its complaint. EcoFactor then filed an amended complaint containing 57 new paragraphs. Google moved to dismiss the amended complaint under Federal Rule of Civil Procedure 12(b)(6), which permits dismissal when a complaint does not state a legally sufficient claim.

Representative Claim

The parties disputed whether independent claim 1 represented the other claims for purposes of the patent-eligibility analysis. The Court treated claim 1 as representative of independent claim 10 and dependent claims 2–9 and 11–18. The Court concluded that EcoFactor had not explained how the additional limitations in those claims meaningfully changed the patent-eligibility analysis. For example, the Court found that some limitations added only generic hardware and that other arguments merely repeated claim language or offered conclusory assertions.

Patent Eligibility

The Court applied the two-step framework from Alice Corp. v. CLS Bank International for determining whether patent claims cover eligible subject matter. At step one, the Court asks whether the claim is directed to an abstract idea. It reaffirmed its earlier conclusion that claim 1 was directed to the abstract idea of accounting for a structure’s thermal mass when evaluating a climate-control system’s operational efficiency. The Court found that the claim was written broadly to cover the general idea of calculating and comparing thermal efficiency, rather than a particular calculation or technological implementation. It also rejected EcoFactor’s argument that the claim required a specific technological improvement and concluded that the claimed process could be performed mentally or with pencil and paper, using conventional computer and networking technology only to perform the process more quickly or efficiently.

At step two, the Court asks whether the claim’s elements, considered individually and together, contain an inventive concept—something more than well-understood, routine, and conventional activity. EcoFactor did not dispute that the individual elements of claim 1 were not inventive, but argued that their ordered combination was unconventional. The Court found that EcoFactor had repeated arguments previously rejected and had not shown why the combination was inventive.

The Court also rejected EcoFactor’s arguments that a dispute over the meaning of “operational efficiency” prevented resolving patent eligibility at the motion-to-dismiss stage. EcoFactor did not explain how its proposed interpretation would affect the analysis, and the Court found that claim 1 was ineligible under all plausible interpretations. Finally, the Court found that additional evidence about EcoFactor’s field trials was insufficient because EcoFactor did not connect that evidence to the patent’s claim limitations.

Disposition

The Court granted Google’s motion to dismiss EcoFactor’s complaint. It found that EcoFactor had not addressed the concerns identified in the prior order and that further leave to amend would be futile. The Court therefore dismissed EcoFactor’s claims with prejudice, directed the Clerk to enter judgment, and ordered the case file closed.
