Rapid growth in patent filings in 3D printing and additive manufacturing over the last decade
What conclusions can we draw from the huge recent growth of patent filings in 3D printing?
There have been a number of changes to the UK Patent Law, including with regard to Web marking, Experimental use exception, and expansion of the Intellectual Property Office’s Patent Opinions Service.
Previously, it was necessary to market a product with the word “patent” or “patented” together with the number of the patent, in order to prevent an infringer claiming to be an “innocent infringer” (someone who can prove that they were not aware of the existence of the patent, and had no reasonable grounds for supposing that the patent existed, at the time of the infringement) and thereby avoiding financial remedies in an infringement action.
As from 1st October 2014, a patent holder has the option to mark their patented product with a web address in order to benefit in the same way. The web address must be of a webpage which clearly sets out the patent number(s) relevant to that product.
In an infringement action, the courts will decide if the notice provided by the webpage is sufficient.
Full guidance on web marking can be found here.
We can provide further advice on how best to comply with the requirements but in brief the following points should be noted:
This change will reduce the burden and costs for patent holders and will make it easier for others to access up-to-date patent information in relation to a product.
Changes to the experimental use exception, otherwise referred to as the research exception, in section 60(5)(b) of the Patents Act were introduced on 1st October 2014. These changes are intended to allow companies to use a patented product, when carrying out testing or other activity to provide information to the regulatory authorities who decide whether a drug should be given a marketing authorisation.
These new provisions do not extent to commercial activities and do not apply retrospectivey to actives carries out before 1st October 2014.
Further information on these changes can be found here.
In 2005 the IPO introduced a Patent Opinions Service to provide an alternative and affordable way for businesses to resolve patent disputes. Previously this service was limited providing opinions on whether or not a patent was infringed by a particular activity and whether or not a patent had the required novelty and inventive step to be a valid patent right. Now the IPO is able to provide opinions on an additional range of matters, including:
In addition, the IPO will be able to start the process of revoking a patent if they issue an opinion indicating that the patent is not new and inventive.
Further information on the changes to the IPO Patent Opinions Service can be found here.
