UTTO Inc. v. Metrotech Corporation

Background

UTTO develops software for locating underground utility lines and other “buried assets.” It alleged that Metrotech’s RTK-Pro Walk Back Feature, provided through firmware, infringed U.S. Patent No. 9,086,441. UTTO asked the court to order Metrotech to stop marketing, promoting, selling, or distributing the feature and similar products embodying the patent’s claims.

UTTO’s requested injunction would have required Metrotech to take affirmative steps, including removing promotional materials and changing advertising, training materials, product literature, and the VMMap Cloud. The court therefore treated the requested relief as a mandatory preliminary injunction, which requires a higher showing than an injunction merely preserving the existing situation.

Likelihood of Success on Infringement

The court focused on the meaning of “group of buried asset data points” in Claim 1 of the patent. It construed that phrase to mean “two or more buried data asset points,” based on the claim’s use of “group” and the plural term “data points,” as well as the patent’s specification and figures.

Metrotech’s walk back feature allowed a user to return to a single previously located point. Because the difference between that feature and the patent’s claimed method was not insubstantial, the court concluded that UTTO had not shown a likelihood of success on either literal infringement or infringement under the doctrine of equivalents. The doctrine of equivalents can apply when differences between an accused product and a patented invention are legally insignificant, but the court found that UTTO had not made that showing here.

Patent Validity

Metrotech also argued that the patent was likely invalid in light of earlier technology, relying in part on the prosecution history of an earlier patent application and prior-art references identified during that proceeding. The court found that Metrotech had raised a substantial question about the patent’s validity. It also noted that UTTO had not offered competing evidence sufficient to eliminate that question.

Irreparable Harm

UTTO argued that Metrotech’s software had caused purchases by some of UTTO’s major clients to stall or collapse, harmed UTTO’s market share, and forced it to offer greater price flexibility. The court recognized that loss of market share can constitute irreparable harm, but found that UTTO’s evidence did not provide enough detail about the alleged loss or explain adequately why monetary damages could not address it. The court therefore concluded that UTTO had not shown likely irreparable harm.

Balance of Equities and Public Interest

Because UTTO had not shown likely success on the merits or irreparable harm, the court could not conclude that the balance of equities and public interest favored an injunction. The court reasoned that imposing an extraordinary injunction would be inequitable and contrary to the public interest when the claim did not appear likely to succeed and the harm did not appear sufficiently severe.

Disposition

Judge William H. Orrick denied UTTO’s motion for a preliminary injunction without prejudice. The court emphasized that the litigation was at an early stage and that later claim-construction briefing or discovery could clarify or change the merits analysis.
