ASM Assembly Systems Weymouth Ltd. et al. v. QTS Engineering, Inc. (18-cv-11214).

ASM Assembly Systems filed a second patent infringement lawsuit against Medway’s QTS Engineering, accusing QTS of infringing U.S. Patents 8,490,545, 8,904, 929 and 9,632,650 through the sale of QTS’ Apshen Stencil Foil Adapter System frames used for .  QTS is said to advertise these frames as being designed for use with the DEK® VectorGuard® High Tension stencil frame, an ASM product.  This is the second such suit in Massachusetts involving the same patents and accused product.  After a claim construction ruling issued in the earlier case, ASM sought to amend the complaint to substitute the named plaintiffs from ASM Assembly Systems Switzerland GmbH and ASM Vectorguard Limited to ASM Assembly Systems Weymouth Ltd. and ASM Assembly Systems LLC, the two named plaintiffs in the instant case, asserting that this was necessary as a result of a restructuring of the companies.  On May 15, 2018,QTS opposed, arguing that the amendment would be futile because at the time of filing of the first complaint, ASM Weymouth already had been assigned all rights and was the only party with standing to sue on the patents.  That motion remains pending.
