BLD Services LLC v. LMK Technologies LLC. Nos. IPR2014-00768, IPR2014-00770, IPR2014-00772, IPR2015-00721 and IPR2015-00723, at the USPTO Patent Trial and Appeal Board.
On August 24, 2015, the PTAB ruled in favor of firm client LMK Technologies, declining institution of inter partes reviews on two petitions filed by BLD Services in 2015. The LMK patents at issue pertain to trenchless sewer pipe rehabilitation, particularly cured in place pipelining, and are the subject of pending district court litigation. BLD previously unsuccessfully challenged the same claims with earlier IPR petitions in 2014.
