Today, Oblon launched its Life Sciences blog, , which is designed to report and comment on Intellectual property matters related to the life sciences industry. This Oblon blog will serve as a resource for quick access to relevant news at the intersection of patent law and Life sciences. With the ever changing landscape of patentability in the life sciences area, ranging from 101, written description, enablement, post-grant challenges, and litigation, our group is focused on keeping abreast of these changes and advising our clients in all aspects of procurement and enforcement. We are now pleased and excited to share this knowledge and insight with the global IP community as a whole in a single focused forum.

This blog is provided and maintained by the Life Sciences practice group, which serves all segments of biotechnology, medical devices, pharmaceuticals and their patentable issues.
