Dr. Teresa Ptashka is a patent agent with extensive experience in patent prosecution of early stage innovations in biology. She works with clients to obtain protection for their inventions and to provide intellectual property that is highly valued by investors.

What do you focus on?

I specialize in obtaining protection for early stage innovations in the U.S. and around the world.

I work with clients to obtain protection for their technologies while also listening and taking into account where they think it will evolve in the coming years.

My technical experience spans the following areas: RNA interference, stem cells, tissue-specific progenitor cells, tissue engineering, drug treatments, repurposed drugs and modulation of cellular signaling or metabolic pathways.

What do you see on the horizon?

Smaller companies will be pressured to increase their pace of development as the U.S. shifts to a first-to-file system, while simultaneously having fewer resources than their big pharma competitors.

  • Maintained and prosecuted a portfolio of U.S. and foreign cases related to RNAi technology.
  • Provide a broad range of patent services (including patent portfolio management) to several academic institutions; assist the institutions in devising and executing strategies that will extract the greatest value from their IP.
