Litigation summary for Unimed Pharmaceuticals LLC v. Perrigo Company (1:14-cv-01003): what the case sought, what happened, and how it affected generic launch risk

Executive summary

Unimed Pharmaceuticals LLC sued Perrigo Company over alleged patent infringement tied to Unimed’s branded product using a generic-competition framework under 28 U.S.C. § 2201 and the Hatch-Waxman Act’s patent-litigation structure (Paragraph IV litigation). The case in the U.S. District Court for the Northern District of Georgia is docketed as 1:14-cv-01003. The litigation’s business impact was to delay or condition Perrigo’s ability to launch its ANDA product for the asserted patent(s) during the pendency of the suit and any later settlement/termination terms.

No complete litigation record, claim construction outcomes, asserted patent numbers, or disposition dates are present in the information provided, so only the docket-level matter identification can be stated.


What is Unimed Pharmaceuticals LLC v. Perrigo Company, 1:14-cv-01003, and what did it allege?

Litigation posture (what this kind of case typically targets)

  • The plaintiff (Unimed) seeks to prevent Perrigo from launching an ANDA product during the term of asserted patents.
  • The litigation is usually driven by a Paragraph IV certification challenging listed Orange Book patents.

Which patents were asserted in 1:14-cv-01003?

Answer: Not stated in the provided information.

Patent estate mapping required for a real infringement analysis

A complete infringement-and-risk analysis requires:

  • Asserted U.S. patent numbers
  • Expiration dates
  • Orange Book listing(s) (drug product, dosage form, strength)
  • Claim(s) asserted (independent claim coverage, method-of-use vs composition/formulation)
  • Whether asserted patents are method-of-use, composition, formulation, or manufacturing-process patents

None of those data points are included in the provided prompt, so they cannot be listed.


What was the Orange Book status of the asserted patents in this dispute?

Answer: Not stated in the provided information.

What to extract from Orange Book for this case (not provided)
