The Court’s decision is in harmony with a number of recent cases invalidating patents that attempted to claim patent protection for “abstract ideas.”

On February 3, 2015, Minitab, Inc. prevailed in a patent infringement suit against EngineRoom, LLC before the U.S. District Court for the Middle District of Pennsylvania. The court issued an order granting Minitab’s Motion for Summary Judgment, invalidating every asserted claim of the three patents-in-suit as unpatentable subject matter under 35 U.S.C. § 101.

EngineRoom’s patents, U.S. Patent Nos. 8,046,190, 8,050,888, and 8,370,107, relate to a method of automated hypothesis testing. Minitab initiated the case in August of 2012 and sought a declaratory judgment of invalidity and non-infringement. EngineRoom counterclaimed for infringement and accused aspects of Minitab 16 Statistical Software of infringing its patents.

Minitab challenged the validity of all three patents by way of a summary judgment motion and asked the Court to determine, as a legal matter, that the claimed inventions in EngineRoom’s patents were not eligible for patent protection.

In granting Minitab’s motion, the Court agreed with Minitab that the patents disclosed an unpatentable, abstract idea and that “requesting and receiving information from a user and displaying the results of various inputs and calculations on a screen are basic, conventional computer activities.” The Court’s decision is in harmony with a number of recent cases invalidating patents that attempted to claim patent protection for “abstract ideas.”

In reaching this conclusion and ruling that the asserted claims of the patents were indeed unpatentable, the Court rejected EngineRoom’s argument that “the patents-in-suit cover a specific inventive, unique way to provide error-proofing for automated hypothesis testing.”

A team from the Palo Alto, Calif. office of the K&L Gates law firm, led by attorney Bryan J. Sinclair, represented Minitab. “The company is very pleased with the outcome, and so is the legal team, who all worked very hard toward obtaining this victory,” Sinclair says.

“Minitab certainly respects intellectual property rights, but felt very strongly that the patents at issue in the case were not valid, for a variety of reasons. We believe that Judge Jones reached a sound and well-reasoned decision that was warranted, given all of the evidence in the case.”

The Court’s order effectively ends EngineRoom’s infringement case against Minitab.
