Jushi Group Co Ltd v OCV Intellectual Capital LLC [2017] EWHC 171 (IPEC)
IPEC trial concerning the validity of a patent claiming a range of glass compositions for use in the making of glass fibre. The claimant alleged that the patent was anticipated by and/or obvious over an earlier US patent describing an overlapping range of glass compositions and example compositions falling within that range. The Court rejected the attacks, holding that that skilled person would not seriously contemplate working within the area of overlap and would not consider it obvious to modify the example compositions so as to bring them within the area of overlap.
Hugo Cuddigan QC acted for the Claimant and Tom Alkin for the Defendant.
