Webinar: Claim drafting chemistry

Online: 04.09.2024

Starts: 04.09.2024 10:00hrs
Ends: 04.09.2024 11:00hrs




Claims both define the invention and delimit the scope of protection. Thus, they are at the core of every patent and yet was face the daily challenge to formulate claims that are just narrow enough and still inventive, while being clear. Let’s explore the many ways to define inventions in the chemical field, e.g. by product and process claims, use claims or chimeric mixtures of these, such as product-by-process claims or medical use claims. To that end, the chemical drafter toolbox must include: functional features, parameters, ranges, disclaimers and Markush formulae. Finally, the claims must zero-in on the technical effects often required for achieving chemical selection inventions, synergies, structure-activity-relationships or even more advanced evergreening techniques.

The webinar will be recorded and then only made available on our epi-learning platform to participants who have registered for the webinar.
