Plastic Patent Disputes – In Recent News


What is a Patent?

As per World Intellectual Property Organization (WIPO), a patent is an exclusive right granted for an invention, which is a product or process that provides, in general, a new way of doing something, or offers a new technical solution to a problem.

Without the consent of the patent owner, the invention cannot be commercially made, used, distributed, imported or sold.

Some Patent Statistics:

  • As per the report published on the website of University of Southern California, world’s first patent, related to technological invention, was granted to Ser Franciscus Petri of Rhodes by the Great Council of Venice in the year 1416
  • As per the survey conducted by the website in December 2020, in the year 1990 about 9,97,501 patents were filed worldwide; which has increased to about 32,24,200 in the year 2019. This is an increase of whooping 223%!
  • Table below provides the list of top 10 patent offices based on the number of the filed patent applications in the year 2019:
Sr. No.Country NamePatents Applications Filed
2The United States of America621453
4South Korea218975
5European Patent Office181479
  • Thus, it can be observed from the table that patent applications filed in the Chinese Patent Office are highest and the number is more than double compared to the second ranked patent office – US. The number of patents filed in Indian patent office are just about 3.8% of those filed in the Chinese Patent Office! A long way to go for India for sure. Moreover, of the total patents filed in various patent offices of the world about 43% are filed in China.
  • Indian Patent Scenario: Please check below the statistical graph published in the website providing details on the number of patents filed, examined, granted and disposed in India from 2014-15 to 2019-20.

Patent Infringement

Exclusive rights of the patent owner are:

  • Protection against infringement
  • Possibility of assigning or licensing the right, in part or in whole

WIPO provides below details on patent infringement:

  • An infringement of the exclusive right of a patent owner involves the unauthorized exploitation of the patented invention by a third party.
  • The making of the invention in particular, and its development for industrial application, usually involve considerable expense for the applicant and for the future owner of the patent for invention.
  • The patent owner thus wishes to recover this expense through exploitation of the patented invention, in particular through the sale of products that incorporate the invention.

Thus, infringement of patent rights in some or the other form leads to the creation of disputes.

(2) The product employs known art, which does not constitute infringement. Further, Milliken’s patent lacks novelty and inventiveness and should be invalidated.
