Pharmaceutical patents for inventions resulting from combination of previously known active ingredients face higher level of scrutiny from the patent examiner as patent office does not generally allow the patent owners to extend the life of existing patents by filing new patents for substantially same or similar inventions, without any novelty or inventive step (non-obviousness).

Evergreening of Patents

Q. What is evergreening of patents?

Such strategies are commonly followed in pharmaceutical sector for drug patents and hence, patent offices rely on the determination of a new or a non-obvious synergy or a distinct effect. In use, such a novel and non-obvious synergy or the distinct effect has to be covered comprehensively by drafting a strong and focused set of patent claims, which can be further supported by way of accompanying detailed description of the invention including results of clinical (laboratory) and biology test results.

Therefore, while drafting patent applications covering drug patents and pharmaceutical inventions, pharma patent attorneys follow the best practice of writing patent specifications with the required detailed description of the inventions to satisfy the patent eligibility criteria.

Patent Thicket

Q. What is a patent thicket?

Another term related to evergreening of patents is patent thicket, which implies a dense web of overlapping intellectual property rights that a company must hack its way through in order to actually commercialize new technology, in other words, “an overlapping set of patent rights” which requires innovators to reach licensing deals for multiple patents from multiple sources.

Product Hopping

Q. What is product hopping in pharmaceutical sector?

As it is well known, pharmaceutical sector often experiences battle between generic drug makers and multinational pharmaceutical companies, which results in “product-switching” or “product hopping”, whereby brand name pharmaceutical companies make an effort to block generic drug manufacturers, which are their competitors, on a patented drug by making slightly different reformulations that offer little or no therapeutic advantages.
