Patent infringement case on docket in federal court

Monday morning attorneys and employees of the Atlanta law firm Alston Bird brought a mountain of evidence and court documents into the U.S. District Courthouse in downtown Columbus.

The evidence is part of a long-running patent infringement case involving pet-health companies.

The attorneys are scheduled to appear before U.S. District Court Judge Clay Land today in an evidenciary hearing. Land ruled in 2011 that sales of PetArmor Plus by Cipla and Velcera had infringed on patents held by Merial.

The legal battle dates back to 2007.
