I own a small business designing software for patent attorneys (as well as being a patent attorney myself) and I frequently use Karen as a reference when trying to decipher the nuances of IP Law and the operations of the US PTO. She's a very clear thinker and really knows her stuff, and I have greatly benefited from her input over the past ten years.

Karen Oster gives good business advice. She knows how to assess a client's needs, whether the client is an individual person or a large corporation. Karen's patent documents are notable for their exquisite clarity, and her track record of successes is impressive. Her ability to stimulate a company's innovation and to provide a valuable Intellectual Property portfolio can be summed up in two words: "impressive" and "reliable."

I endorse this lawyer's work. She is very knowledgeable about the intricacies of practice before the U.S. Patent & Trademark Office. I have seen samples of her work and have been very impressed by their quality.

Help your colleagues, build your professional network, and increase your exposure.
