Reuben Jacob and Fiona Kellas, Maucher Jenkins share their expertise on IP strategies and considerations for gene therapy inventions.

Gene therapy enables the treatment of a disorder or disease through the insertion of a gene into a patients cells instead of using drugs or surgery.This technique involves the introduction of genetic material into cells to compensate for abnormal genes in the patient or to make protein that will be beneficial to the patient.As an example, if a mutated gene causes a protein that is necessary for the correct functioning of cells to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.Gene therapy is understood to be useful in the treatment of a range of conditions such as cancer, cystic fibrosis, muscular dystrophy and Alzheimers disease.

UK role in gene therapy techR&D

Gene therapy is considered to be very important to the future of medicine and as such, many companies are focussing their research and development into gene therapy technologies.The UK is a growing industry for research into these areas and it is anticipated that by 2035 the UK industry around cell and gene therapy technologies will be worth in the region of 10 billion.Gene therapy research is still at an early stage.Due to this length of time and the associated costs involved in developing an effective gene therapy and taking it through to approval, it will be important for companies working in this area to put into place an effective IP strategy that will provide protection for their inventions and assist them in maintaining their market position.In addition, the competitive nature of the gene therapy industry means that will be important for a company to obtain patent protection for inventions being developed, as well as reviewing the patent landscape to check that the company is free to operate in their chosen area.

What makes something patentable?

In order for an invention to be patentable, it must be new, inventive and capable of industrial application.In addition to the requirement that an invention meets the above requirements of patentability, it is also important that the invention does not contain subject matter that is excluded from patentability.One of the challenges associated with obtaining patent protection for gene therapy inventions is that the European and US patent systems include a number of exceptions to patentability that are relevant to biological material and natural products.In Europe, it is not possible to obtain patent protection for a method of treatment or surgery of the human body.Thus, the removal of cells from a patient would not be considered to be patentable in Europe.In addition, inventions relating to stem cells that are derived from the destruction of human embryos are not patentable in Europe.In the US, recent case law (Molecular Pathology v Myriad Genetics, Inc, 2013) has meant that inventions relating to natural phenomena and natural products must show characteristics that are different to their natural counterpart(s).

However, despite the above challenges, there are a number of aspects of the gene therapy technology that may be eligible for patent protection.Typically, the gene therapy procedure can involve performing the required modification procedure on cells that have been removed from a patient before reintroducing the cells into the subject to produce their modified effect.The process of modifying the cells may be patentable if it fulfils the above requirements of patentability.In addition, it may be possible to obtain protection for the methods that are used to culture, manipulate or modify the cells that are used for gene therapy.

At Maucher Jenkins, we have a team of attorneys who can provide IP advice and assistance in the area of patenting inventions involving gene therapy, molecular biology and biochemistry.
