Judge Robinson: Counterclaims and Inequitable Conduct Claims Allowed to Proceed

Judge Robinson recently considered various motions related to counterclaims in Butamax Advanced Biofuels LLC v. Gevo, Inc., C.A. No. 11-54-SLR (D. Del. June 21, 2012). She first denied Butamax’s motion for judgment of non-infringement on the pleadings, declining “to tackle the issues of claim construction and infringement without the benefit of any introductions to the technology or to the accused ‘product’ but for Butamax’s assertions regarding same. If, however, there are a limited number of critical claim limitations, the court would entertain a course of focused discovery in order to encourage an expedited resolution of the counterclaims.” Id. at 2-3.

Judge Robinson also granted Butamax’s motion to sever counterclaims and try them separately, id. at 3, and Butamax’s motion to amend the pleadings to add allegations of inequitable conduct. She rejected Gevo’s argument that the amendments were intended “to delay the adjudication of Gevo’s counterclaims” and found that Butamax had pled inequitable conduct with sufficient particularly and that its allegations were not futile. Because the “proposed amendment satisfies the . . . pleading standard by identifying the ‘who,’ the ‘what,’ the ‘when,’ the ‘where,’ and the ‘how,’” Judge Robinson allowed the amendment. Id. at 4-6.
