However, the perceived value in having lots of patents filed is often misguided. In life sciences especially, it can be as important to have one patent, which is valid and broad enough to cover multiple competitors, than multiple patents which are weak or narrow in scope. SMEs should bear this in mind: quality and not quantity is often a differentiating factor.The real question investors will want to ask themselves is whether the patents have any value.At the heart of the answer to this question is whether the patents are actually valid. It is not unusual to see tens of pages in a patent application, but that does not mean it is worth anything. It can be relatively easy to create what looks like a significant patent portfolio for an unsophisticated investor.
It can be important, therefore, to scratch beneath the surface and consider whether patents applied for will actually be granted and how broad the level of any patent protection is. Patents do not confer a right to do something. They provide a right to stop others doing it – so a valuable asset will be one which is wide enough to catch multiple competitors.
There can be good reasons why some companies have lots of patents and others have very few – a company with a limited portfolio is not necessarily a bad investment choice and one with lots of patents is not necessarily a good one.
To be of any value, patents need to be owned by the right person. This can be a complicated area where there have been many different parties involved in developing a new product or process. Investors must undertake their due diligence with care to ensure that the correct chain of title for such rights is in place.
There are two major strategic decisions a biotech has to make to ensure they get a proportionate portfolio of high quality.
When to file any patent?
There is a constant tension between getting there first and having enough data to ensure your patent can withstand challenge. Factor into that dilemma the fact that many biotechs, especially university spin-out companies, have academics at the helm who, often encouraged by the university or the scientific community, want to publish their work early – such an approach would be a death knell to any hope of getting a patent and often puts pressure on biotechs to file early.
A good example of why this matters is the huge ongoing global debate over who filed protection first for 'CRISPR', a technology which enables people to edit genes simpler, faster and more economically than ever before. It is a platform technology – so has a vast array of potential applications, not just therapeutic but for example in developing new species to clean up oil spoils or to ensure new-born babies are resistant to HIV. It is worth billions, but a big battle is ongoing which turns on whether the key patents were filed too early.
Where to file?
Maintaining a patent portfolio, especially a global one, can be extremely costly, so companies have to decide where to file.
A strategy focused on important markets for the company and where competitors operate, as opposed to a global filing programme, can often be the best approach for a biotech.
