Ignorance is not bliss. Before any significant moneys are spent on R&D or Product Development, a basic FTO (freedom to operate) search you be performed to ensure the idea, technology, or product is not infringing the IP rights of another party. IPstreet.com's search tools will help you avoid third-party infringement.
When approached with this legal assertion, as a patent counselor for your client, you need insights to help you define and determine your defense. No, I am not: A patent is defined by its language, and many times, proper preparation for a Markman Hearing, or Claim Construction Hearing, can determine the summary judgment. If you are accused of infringing on a claim, you want to find ways to minimize the scope of the claim [on the other hand, if you are accusing, you want to broaden a claim's scope]. With IP Street, you can scrutinize a claim in various ways. Your patent is invalid: Since the USPTO granted the patent, the presumption is that all of its claims are valid. Anyone can challenge the validity of a patent (request re-examination) whether or not an infringement injunction has been made. [Normally, when the USPTO learns of an infringement lawsuit, out of due diligence, they open a re-examination case.] The quickest path to invalidate a patent is to identify prior art.
In Article I, Section 8 of the Constitution of the United States it says, " Congress shall have power [...] to promote the progress of science and useful arts by securing for limited times to inventors the exclusive right to their respective discoveries."
Myopia is generally what happens when unprecedented opportunities are placed before them. Those in the know generally do better than those in the worry. Consider Cetus, a startup biotech with a focus on a liver drug. The FDA delayed the approval of the drug, and a major funding crisis ensued. Chiron offered to take over the liabilities contingent on the sale of two patents (# 4,683,202 and # 4,683,195) to a third party, Roche Molecule for $300M (in 1993). This sale was stalled because DuPont challenged the validity of the patents, based on the formal claims written by the inventor (not a patent attorney), Kary Mullis. In the end, the soap opera turned out well for the investors with weak constitutions. For $300M, they sold the two patents to Roche, turned the company over to Chiron, and walked away. Kary Mullis won the Nobel prize for his invention embedded in these two patents, known as polymerase chain reaction (PCR) which allows DNA to be cloned. Over 4000 patents in biotech cite these original two patents. In our estimation, $300M represents "pennies on the dollar" valuation of these patents. The shareholders got a payday, and left the game. Roche on the other hand is thriving based on its intangible assets. Let IPstreet.com assist you.
