Causam Enterprises, Inc. v. Ecobee Technologies ULC

Causam · United States Court of Appeals for the Federal Circuit · October 15, 2025 · No. 24-1958

Summary

The United States Court of Appeals for the Federal Circuit affirmed the Patent Trial and Appeal Board’s decision holding claims 1–11 and 13–19 of Causam’s ’268 patent unpatentable for obviousness. The court held that Causam had constitutional standing to appeal based on record evidence establishing its ownership of the patent, but could not assert the due-process rights of an alleged third-party owner. The court also upheld the Board’s construction of the claim limitation concerning measurement and verification data and found no reversible error in the obviousness determination.

Questions Presented

  1. Whether Causam had Article III standing to appeal the Board's inter partes-review decision.
  2. Whether the Board committed a constitutional due-process error by declining to determine whether Causam was the true owner of the patent.
  3. Whether the Board properly construed the claim limitation requiring generation of measurement and verification data corresponding to a reduction in consumed power.
  4. Whether the Board's obviousness determination could stand after the challenged claim construction.

Holdings

  1. Causam had constitutional standing because record evidence, including its status as assignee of record and its unequivocal assertions of ownership, was sufficient under the summary-judgment-like burden applicable to an appellant from an agency proceeding.
  2. Causam could not assert the alleged true owner's due-process rights because litigants generally may not assert the constitutional rights of third parties, and Causam lacked the close relationship and aligned interests necessary for third-party standing.
  3. The Board correctly construed the limitation requiring generation of measurement and verification data corresponding to a reduction in consumed power as not temporally restricted to measurements generated during a demand-response event.

Key quotations

That burden requires an appellant to “either identify . . . record evidence sufficient to support its standing to seek review or, if there is none because standing was not an issue before the agency, submit additional evidence to the court of appeals.” (6-7)
The language of limitation [1c] does not support Causam’s narrow construction. The claim itself simply does not provide any indication that the “measurement and verification” component is temporally restricted to being performed during a demand response event. (10)

Factual background

Causam is the recorded owner and assignee of U.S. Patent No. 10,394,268, which concerns techniques for actively managing electric-power consumption and tracking power savings. Ecobee petitioned for inter partes review of all claims except claim 12, asserting that the challenged claims were obvious over Ehlers or Ehlers combined with Chen. Causam argued that the Board should not consider the petition because of a disputed ownership issue and separately argued that the Board misconstrued a limitation requiring generation of measurement and verification data corresponding to reduced power consumption.

Procedural history

Ecobee petitioned for inter partes review of claims 1-11 and 13-19 of U.S. Patent No. 10,394,268. The Board instituted review and issued a final written decision on March 19, 2024, holding each challenged claim unpatentable under 35 U.S.C. § 103 over Ehlers or Ehlers in view of Chen. The Director denied review on April 11, 2024, and Causam timely appealed to the Federal Circuit, which affirmed.
