  • making,

  • using,

  • offering for sale,

  • selling” the invention in the United Kingdom

  • “importing” the invention into the United Kingdom

Point to be remembered here is: it is right to exclude others!!! That is you can stop others... hence it is your (patent owners) responsibility to enforce the patent, and stop others from copying your patented invention without your consent or permission (something called patent infringement).

Stage 3: Opinion about patentability

Upon receiving the novelty search report for your invention, next step is a critical review by patent attorney to build an opinion about patentability of your invention. Here the cost defers based on complexity of invention and number of closely associated prior arts found in the research. This opinion tells you (inventor) whether the invention is patentable or not.
