Advanced Steel Recovery, LLC (“ASR”)
– Successfully moved to dismiss, without leave to amend, a number of the defendants’ business tort and related counterclaims asserted in response to ASR’s patent infringement claim. 

– Sued the defendants for patent infringement alleging that certain technology to load scrap or other materials into sea containers infringed ASR’s patent. Defendants moved to dismiss ASR’s first amended complaint and/or moved for summary judgment, arguing that the asserted patent claims were not supported by a prior parent patent application, and that they were invalid because the accused product pre-dated the effective filing date of the application for ASR’s asserted patent. The Court ruled in ASR’s favor, finding that ASR has sufficiently pled a claim for patent infringement, that genuine disputes of material fact existed to preclude summary judgment, and that sanctions were unwarranted.
