What is patent, types of patent and generate patent ideas (Patent Definition)

Patent, types of patent and generate patent ideas              

                 A patent is a set of exclusive rights granted by a sovereign state to an inventor or assignee for a limited period of time in exchange for detailed public disclosure of an invention. An invention is a solution to a specific technological problem and is a product or a process.

               Innovation was defined as a complex series of activities beginning when the original idea is conceived (conception), proceeding through a succession of interwoven steps of research, development, engineering design, market analysis, management decision making, and so on, and ending when an industrially successful product (which may be a thing, a technique, or a process) is accepted in the marketplace.

Parts of patent :
  1. a title;
  2. a cross-reference to other related patent applications which have already been filed;
  3. a section describing the background and general technical area of the invention, which will sometimes include reasons why prior inventions are lacking;
  4. a summary of the invention;
  5. a description of the contents in any drawings;
  6. a detailed description of the invention;
  7. a series of examples used to illustrate how the invention is made, used, or is different from the prior art;
  8. a listing of desired claims; and,
  9. an abstract describing the invention in a general way so that the invention can be easily searched.

Types of patent :
  • Utility Patents
  • Utility Model Patents
  • Design Patents
  • Plant Patents

Following are some of the ways to think to generate patent ideas:

  • Have deep knowledge on the domain and have diverse knowledge.
  • Combine two ideas into one or make the existing one better.
  • Perform prior search whether same exists or some one have patented.
  • Document all the research and work which you have done to keep track in future.
