Fiduciary Duty to Assign Patent Rights Does Not Guarantee Assignment

Schultz v. iGPS Co., No. 10 C 71, Slip Op. (N.D. Ill. Aug. 16, 2011) (Hibbler, Sen. J.).

Judge Hibbler denied defendants' motion to dismiss plaintiff's patent infringement complaint for lack of standing. Defendants argued that plaintiffs did not hold enforceable title to the patents in suit. The patents in suit were intentionally abandoned by plaintiff's co-owner, CHEP. When plaintiff learned of the abandonment, he asked the Patent Office to revive the patents, explaining that his failure to pay the maintenance fee was inadvertent. The only way plaintiff could truthfully claim inadvertence was if he referred only to himself and not CHEP, which intentionally abandoned. As such plaintiff was estopped from arguing that he also revived CHEP's rights. Defendants argued that plaintiff had a fiduciary duty to assign his rights to his then employer, VTEC. But because VTEC never required plaintiff to assign his rights, the Court held that plaintiff had retained the remaining rights in the patents in suit based upon the facts alleged in the complaint. Plaintiff, therefore, had standing to sue.

Patent Assignor Estoppel is Limited to the Assignee

Schultz v. iGPS Co. LLC, No. 10 C 71, Slip. Op. (N.D. Ill. Jan. 3, 2011) (Hibbler, Sen. J.)

Judge Hibbler granted in part defendant's Fed. R. Civ. P. 15 motion to amend its affirmative defenses. The doctrine of assignor estoppel did not ban defendant's invalidity and inequitable conduct defenses. An assignor is estopped from challenging the validity and enforceability of its assigned patent, but that estoppel is personal to the assignee. Because plaintiff was not the assignee, he had no right to assert estoppel. Furthermore, to determine whether defendants were in privity with the assignor would require facts beyond the complaint and was, therefore, not resolvable in a motion to dismiss.

The Court, however, did not accept defendants' inequitable conduct defenses because they failed to plead the necessary intent with particularity. Defendants only alleged that patentee failed to pay its maintenance fees and then improperly revived the patents, without more. Defendants were granted leave to replead those defenses, if possible, with sufficient facts.
