DS Advanced Enterprises, Ltd. v. Lowe’s Home Centers, LLC

Summary

The United States District Court for the Southern District of California denied Lowe’s Home Centers, LLC’s motion for attorneys’ fees and expenses under 35 U.S.C. § 285 and 35 U.S.C. § 1927. Although the court found that DS Advanced’s proposed claim construction was incorrect and strained the plain meaning of the patent, it did not find the case exceptional or conclude that plaintiff’s counsel acted in bad faith or unreasonably multiplied the proceedings. The order was issued after summary judgment of non-infringement and was dated February 24, 2025.

Holdings

1. Lowe's motion for attorney fees was timely because the court had not yet entered final judgment and had specifically contemplated an exceptional-case determination after final judgment.
2. The case was not exceptional under § 285, and Lowe's was not entitled to attorney fees and expenses, because DS Advanced's unsuccessful claim construction, although strained and objectively weak, was not shown to have been asserted in bad faith or for an improper purpose when the totality of the circumstances was considered.
3. Lowe's was not entitled to fees against DS Advanced's counsel under § 1927 because the record did not establish that counsel intentionally and in bad faith unreasonably multiplied the proceedings.

Questions Presented

1. Whether the patent infringement action was exceptional under 35 U.S.C. § 285 because DS Advanced pursued an objectively unreasonable claim construction or litigated in an unreasonable manner.
2. Whether Lowe's motion for attorney fees under 35 U.S.C. § 285 was timely despite being filed before entry of final judgment.
3. Whether DS Advanced's counsel intentionally and in bad faith unreasonably and vexatiously multiplied the proceedings within the meaning of 28 U.S.C. § 1927.
