This Time It’s Personal(ized): Pharmaceutical Companies, Dosing Regimen Patents, and Personalized Medicine

Peter Selness, MJLST Staffer

An area of developing healthcare garnering attention in both the medical community and areas of intellectual property law is that of personalized medicine.   Personalized medicine changes the old one-size-fit-all approach of medication dosing to instead tailor medications to each individual patient based upon their genetic make-up.  This practice promises numerous benefits for patient healthcare, but also has some substantial road blocks to overcome before becoming a reality.  Among the issues facing this field of medicine is the controversy surrounding the patentability of personalized medicine methods.  Several recent cases such as Mayo Collaborative Services v. Prometheus Laboratories and Association for Molecular Pathology v. Myriad Genetics, Inc. have raised serious concerns over whether or not personalized medicine methods are based on patentable subject matter.

This concern was taken one step further in the recent article Decline of Dosage Regimen Patents in Light of Emerging Next-Generation DNA Sequencing Technology and Possible Strategic Responses, which discussed the potential impact this may have on the pharmaceutical industry.  Among the concerns addressed was the impact of not being able to obtain patents on dosing regimens for drugs developed by pharmaceutical companies.  While a pharmaceutical company should have no problem patenting a novel medication it has developed, adding additional patent protection to its patent portfolio surrounding that product, such as patents on dosing regimens, has long been a practice utilized to keep competitors at bay.  Considering the massive investment in research and development required to bring a new drug to market (sometimes billions of dollars), pharmaceutical companies are rightly alarmed by any potential loss of patent protection they may experience on their product.  As the article mentioned, this issue will also surely be compounded by the transition to personalized medicine and integrated healthcare, but it may also be a self-solving problem.

Though the article is concerned with the impact personalized medicine may have on pharmaceutical companies if they no longer can obtain patent protection on dosing regimens, researchers developing personalized medicine methods currently face the same issues.  In order for personalized medicine to have an impact on pharmaceutical companies, it must be a fully developed method that has been integrated into everyday healthcare practices.  For that to happen, researchers must have a fundamental understanding of what specific genes give rise to differences in patients’ responses to medication.  This has proven to be a long and expensive process requiring the systematic sequencing of millions of genes from numerous subpopulations of patients; and all of this work is expensive.  Given that the end result of personalized medicine research is a method of administering medication based on an individual’s genetic make-up, patents on personalized medicine fall victim to the same issue facing pharmaceutical companies’ dosing regimen patents.

Lacking the ability to obtain patent protection on personalized medicine methods, the economic feasibility of research in this area becomes more questionable.  To circumvent this dilemma, those within the field of personalized medicine will most certainly be looking for the same solutions as pharmaceutical companies.  Therefore, one of two results will likely occur, both of which may solve the issues of dosing regimen patentability facing the pharmaceutical companies.  One possibility is that the field of personalized medicine will be unable to economically sustain future research without patent protection and fully integrated healthcare will never become a reality; making this issue disappear for pharmaceutical companies.  The other, more likely, possibility is that in order for research in the field of personalized medicine to continue, those researchers will solve the very dilemma that pharmaceutical companies fear will be brought about by the emergence of integrated healthcare.  Either way, pharmaceutical companies’ dosing regimen patents are so closely tied to the fate of personalized medicine patents that the emergence of integrated healthcare most likely cannot occur in a manner that will be detrimental to pharmaceutical companies’ patent portfolio.
