What is PatentK

A patent is a form of intellectual property that gives its owner the legal right to exclude others from making, using, selling and importing an invention for a limited period of years, in exchange for publishing an enabling public disclosure of the invention. In most countries, patent rights fall under civil law and the patent holder needs to sue someone infringing the patent in order to enforce his or her rights. In some industries patents are an essential form of competitive advantage; in others they are irrelevant. The procedure for granting patents, requirements placed on the patentee, and the extent of the exclusive rights vary widely between countries according to national laws and international agreements. Typically, however, a patent application must include one or more claims that define the invention. A patent may include many claims, each of which defines a specific property right. These claims must meet relevant patentability requirements, such as novelty, usefulness, and non-obviousness. Under the World Trade Organization’s (WTO) TRIPS Agreement, patents should be available in WTO member states for any invention, in all fields of technology, provided they are new, involve an inventive step, and are capable of industrial application. Nevertheless, there are variations on what is patentable subject matter from country to country, also among WTO member states. TRIPS also provides that the term of protection available should be a minimum of twenty years.

We are scientists! patent lawyers & scientists
We replace a non-technical patent lawyer!
We are experts in your domain knowledge!

It helps to have a Ph.D. degree to better understand an invention and search journal articles more effectively. Our senior scientists’ broad science background is beneficial to the patent work with a broad range of domains like software, digital signal processing, mechanic, electronics, physics, pharmaceutical, food science, and biotechnology, etc. industries. A patent scientist is a patent professional who is typically involved in preparing and prosecuting patent applications. The terms are usually applied to patent professionals with advanced scientific or engineering backgrounds. In general, the position involves many of the technical aspects of patent prosecution, including doing background and prior art searches, drafting the specifications and preparing reference figures for patent applications, and giving technical expertise during invention evaluation. Work of this nature may focus a great deal of research and development while including patent considerations.

Why Us

This is why we can write BETTER and FASTER, and save you trouble and time. Best patent for LESS.

✩ We are so confident in our work that your satisfaction and patent success are guaranteed (100% warranty). PatentK will continue to work on your case without additional charge until it is granted. No other lawyers will promise you this.

✩ Our prices are so competitive that they are normally only one-third or one-quarter of the market prices.

✩ All your patent information is strictly confidential with us. PatentK signs NDAs and service contracts.

Here is what our customers describing our services:

PatentK provided professional and excellent service for our patent application process. He was able to… take a basic patent document and turn it into a fully completed, detailed and, most importantly, accurate patent application. He had excellent knowledge of the subject matter, which is rare, as our technology is proprietary. This meant very little changes were required and saved time. We highly recommend them to others.

“I decided to work with PatentK for my first patent application because it has many years of professional experience in the field. My whole experience was so pleasant and smooth. All I needed to do was explaining my idea and answering their questions. Then they translated the idea into a well-written patent application. First, “If they understand your idea, you are all set.” All I needed to do was to make sure PatentK’s scientist fully understand the concept of my invention. They might come up with some very high-quality clarification questions. Once I cleared all the questions, PatentK set out to finish the drawings and descriptions in a very efficient way. Second, “The document quality is beyond my expectations.”

I have to say that I made the right decision to use PatentK instead of writing by myself though I had extensive academic writing training through my Ph.D. studies. When I was reviewing the first draft that PatentK had sent to me, I felt it was so well-considered, well-written, and with very high quality. English was so beautiful, professional, and neat. It is beyond all my expectations. Third, “The claims demonstrate PatentK’s solid many years’ professional experience in the field.” The claim portion that PatentK put up was so professional and nicely-protected through multiple angles. Although I had previously read some articles about how to protect a patent, the claims PatentK wrote were very eye-opening for me. I felt that I had found the right company to file my patents because one cannot write as good claims as PatentK does without the same extensive experience. I recommend PatentK without reservation. If your invention is important to you, look no further as PatentK is your best choice.”
