Swedish diaper company SCA Hygiene’s patent claim has dismissed under lashes and equitable estoppels, Law360 reported.

The company filed its patent titled “Absorbent pants-type diapers” in 1992 but granted by US Patent Office in 2002. (Patent No. 6,375,646) They found out the infringement by its rival company, First Quality, since 2003. First Quality responded that the SCA’s patent was not valid, and sent a letter informing their patent rights.  SCA didn’t take any further legal actions about it until 2010. They said that they were reexamining their rights and getting new counsel, but the judge said they took too long to take actions against First Quality.
