  • 10. Background • Distinguish the invention from what is already existing in the field • Should not describe the claimed Invention • Should use drawings to explain any prior art • If the latest art in the field (prior to the invention at hand) is Applicants own work , then such work should not be described here • Do not exaggerate/criticize the disadvantages of prior art
  • 11. Objects • Should set forth broad objectives • Acts as a pointer while drafting detailed description
  • 12. Statement of invention • Usually drafted when omnibus claims are intended to be introduced. • According to new manual of patent office practice and procedure (MPPP), Omnibus claim should be avoided. • Paraphrasing of independent claims
  • 13. Brief description of drawings • Should clearly indicate that the drawings are showing embodiments of the invention and not the invention itself • Should start with “…The invention is illustrated in the accompanying drawings, throughout which like reference letters indicate corresponding parts in the various figures. The embodiments herein will be better understood from the following description with reference to the drawings, in which:…”

Detailed description • Should provide sufficient details of the invention • The making and using of the invention should be explained in depth so as to enable a person having ordinary skill in the art to practice the invention • Details of the invention should be explained with reference to drawings • Should disclose best mode
  • 15. Detailed description • Should provide sufficient details of the invention • The making and using of the invention should be explained in depth so as to enable a person having ordinary skill in the art to practice the invention • Details of the invention should be explained with reference to drawings • Should disclose best mode
  • 16. Detailed description • The terminology should be consistent • Should be well organized and easily understandable • Start with a general overview and proceed with increasing levels of detail • Should set forth several, if not all, alternative working examples even if only one embodiment is illustrated in the drawings
  • 17. Claims • Should start in a different page • Should start with Preamble I/We Claim • Define the scope of protection • Every claim has a date associated with it • Every claim is an invention • What is not claimed in the “claims” stands disclaimed
