A company's patent was deemed obvious based on existing knowledge. Their attempt to appeal this decision was rejected because their arguments weren't strong enough and they should have raised them earlier.
Key Facts
- •Samsung Bioepis UK Limited (Claimant) sued Janssen Biotech, Inc. (Defendant) for patent infringement.
- •The patent was held invalid for obviousness over the 'Sands Slides' document.
- •The appeal focuses on the interpretation of 'corticosteroid-free clinical remission (CSFCR)' in the patent claim.
- •The judge found that the patent claim does not require patients to be steroid-free at the start of treatment, but the drug must be capable of treating both steroid and non-steroid patients.
- •The judge's decision combined findings on the expectation of treatment effect for both steroid and non-steroid patient groups.
- •Janssen argued that combining these groups was impermissible and lacked sufficient evidence.
