Fortress Iron L.P. Digs Into Legal Action Against Digger Specialties for Alleged Patent Infringement

Fortress Iron L.P. filed a lawsuit against Digger Specialties, Inc. for patent infringement, alleging that Digger’s Westbury VertiCable Aluminum Railing violates Fortress’s U.S. Patents 11,643,838 (the “‘838 Patent”) and 12,180,735 (the “‘735 Patent”). The complaint states that Fortress, a Texas-based company, is the owner of the patents protecting its FortressCable V-Series steel cable railing systemv. Meanwhile, the court documents assert that Digger, based in Indiana, produces a similar product and has reportedly continued to sell it despite being notified of the alleged infringement.

The lawsuit claims that Digger’s product infringes on the patents, particularly regarding features such as the design of vertical cable barriers and adjustable end members for tension control. Fortress seeks monetary damages, treble damages for willful infringement, and an injunction to stop Digger from continuing to sell the infringing product.

The case has been assigned to Judge Damon R. Leichty and Magistrate Judge Scott J. Frankel in the U.S. District Court of Northern Indiana Case No. 3:25-cv-00099.
