Judge Sleet Claim Construction Order

In a recent ANDA case involving valganciclovir hydrochloride 450 mg tablets, Judge Sleet construed the term “compound 2-(2-amino-l ,6-dihydro-6-oxo-purin-9-yl)methoxy-3-hydroxy-lpropanyl-L-valinate hydrochloride in crystalline form” to mean “valganciclovir hydrochloride in a physical form having molecules arranged in a regularly repeating three dimensional pattern.”
