Case Study: Philochem AG defends core DNA-encoded library patent with Mewburn Ellis

Philochem AG defends EP3083957 through EPO opposition and appeal with Mewburn Ellis

Philochem AG, a Zurich-based leader in DNA-encoded combinatorial libraries, relied on Mewburn Ellis for patent drafting, prosecution, and defense of its core technology. The company faced a challenge when its granted European patent was opposed by a larger competitor.

Mewburn Ellis successfully defended the patent through both EPO opposition and appeal proceedings, with the claims being maintained as granted. This significant victory enhanced the commercial value of Philochem's drug discovery programs and protected its core proprietary technology, representing a notable win for a smaller company against a much larger opponent.
