Patent Infringement Claim Involving Complicated Technology May Require Additional Detail In Complaint

Author:Mr Andrew DeVoogd and Christopher G. Duerden

A recent opinion from the Northern District of Texas is a reminder to all patent practitioners to heed pleading standards when drafting a complaint for patent infringement. In Lexington Luminance LLC v. Service Lighting and Electrical Supplies, Inc. d/b/a, 3-18-cv-01074 (TXND October 9, 2018, Order), the court denied the defendant, Service Lighting and Electrical Supplies, Inc. d/b/a's ("1000bulbs") request to dismiss the case for failure to meet the pleading standard, but granted its alternative request for a more definite statement.

Cir. 2018), its factual allegations were actually sufficient to meet its pleading obligations. According to that case, a pleading in line with Form 18, a pleading example for direct patent infringement claims that has otherwise been abrogated by the Supreme Court, may meet the pleading standard.

The court disagreed, stating that the Federal Circuit...
