Drug patents don't essentially spur corporations to innovate a lot as prohibit entry to their IP. Andrii Zastrozhnov/iStock by way of Getty Photos Plus
Biomedical innovation reached a brand new period throughout the COVID-19 pandemic as drug growth went into overdrive. However the ways in which model corporations license their patented medication grant them market monopoly, stopping different entities from making generics to allow them to completely revenue. This considerably limits the attain of lifesaving medication, particularly to low- and middle-income international locations, or LMICs.
I’m an economist who research innovation and digitization in well being care markets. Rising up in a creating area in China with restricted entry to medicines impressed my curiosity in institutional improvements that may facilitate drug entry. One such innovation is a patent pool, or a “one-stop store” the place entities will pay one low worth for permission to make and distribute all of the therapies lined by the pool. My latest analysis discovered {that a} patent pool geared towards public well being can spur not solely generic drug entry in LMICs but in addition innovation for pharmaceutical corporations.
Patent swimming pools will help improve entry to costly medication.
Drug patents within the international panorama
Patents are designed to offer incentives for innovation by granting monopoly energy to patent holders for a time frame, usually 20 years from the appliance submitting date.
Nonetheless, this intention is sophisticated by strategic patenting. For instance, corporations can delay the creation of generic variations of a drug by acquiring further patents based mostly on slight modifications to its formulation or methodology of use, amongst different techniques. This “evergreens” the corporate’s patent portfolio with out requiring substantial new investments in analysis and growth.
Moreover, as a result of patents are jurisdiction-specific, patent rights granted within the U.S. don’t routinely apply to different international locations. Corporations usually receive a number of patents overlaying the identical drug in several international locations, adapting claims based mostly on what’s patentable in every jurisdiction.
To incentivize expertise switch to low- and middle-income international locations, member nations of the World Commerce Group signed the 1995 Settlement on Commerce-Associated Points of Mental Property Rights, or TRIPS, which set the minimal requirements for mental property regulation. Beneath TRIPS, governments and generic drug producers in low- and middle-income international locations could infringe on or invalidate patents to carry down patented drug costs below sure circumstances. Patents in LMICs have been additionally strengthened to incentivize corporations from high-income international locations to speculate and commerce with LMICs.
Figuring out what’s patentable may be sophisticated.
The 2001 Doha Declaration clarified the scope of TRIPS, emphasizing that patent laws mustn’t forestall drug entry throughout public well being crises. It additionally allowed obligatory licensing, or the manufacturing of patented merchandise or processes with out the consent of the patent proprietor.
One notable instance of nationwide patent regulation in observe after TRIPS is Novartis’ anticancer drug imatinib (Glivec or Gleevec). In 2013, India’s Supreme Court docket denied Novartis’s patent software for Glivec for obviousness, which means each specialists or most of the people might arrive on the invention themselves with out requiring a lot talent or thought. The difficulty centered on whether or not new types of recognized substances, on this case a crystalline type of imatinib, have been too apparent to be patentable. On the time, Glivec had already been patented in 40 different international locations. On account of India’s landmark ruling, the value of Glivec dropped from 150,000 INR (about US$2,200) to six,000 INR ($88) for one month of remedy.
Patent challenges and swimming pools
Though TRIPS seeks to stability incentives for innovation with entry to patented applied sciences, points with patents nonetheless stay. Drug cocktails, for instance, can include a number of patented compounds, every of which may be owned by completely different corporations. Overlapping patent rights can create a “patent thicket” that blocks commercialization. Therapies for persistent circumstances that require a steady and cheap provide of generics additionally pose a problem, as the price burden of long-term use of patented medication is usually unaffordable for sufferers in low- and middle-income international locations.
One resolution to those drug entry points is patent swimming pools. In distinction to the presently decentralized licensing market, the place every expertise proprietor negotiates individually with every potential licensee, a patent pool offers a “one-stop store” the place licensees can get the rights for a number of patents on the similar time. This may cut back transaction prices, royalty stacking and hold-up issues in drug commercialization.

Patent swimming pools have been first utilized in 1856 for stitching machines and have been as soon as ubiquitous throughout a number of industries. Patent swimming pools step by step disappeared after a 1945 U.S. Supreme Court docket determination that elevated regulatory scrutiny, hindering the formation of latest swimming pools. Patent swimming pools have been later revived within the Nineties in response to licensing challenges within the data and communication expertise sector.
The Medicines Patent Pool
Regardless of many challenges, the primary patent pool created for the aim of selling public well being fashioned in 2010 with assist from the United Nations and Unitaid. The Medicines Patent Pool, or MPP, goals to spur generic licensing for patented medication that deal with ailments disproportionately affecting low- and middle-income international locations. Initially overlaying solely HIV medication, the MPP later expanded to incorporate hepatitis C and tuberculosis medication, many medicines on the World Well being Group’s important medicines listing and, most just lately, COVID-19 therapies and applied sciences.
However how a lot has the MPP improved drug entry?
I sought to reply this query by analyzing how the Medicines Patent Pool has affected generic drug distribution in low- and middle-income international locations and biomedical analysis and growth within the U.S. To investigate the MPP’s affect on increasing entry to generic medication, I collected knowledge on drug licensing contracts, procurement, private and non-private patents and different financial variables from over 100 low- and middle-income international locations. To investigate the MPP’s affect on pharmaceutical innovation, I examined knowledge on new medical trials and new drug approvals over this era. This knowledge spanned from 2000 to 2017.

I discovered that the MPP led to a 7% improve within the share of generic medication equipped to LMICs. Will increase have been larger in international locations the place medication are patented and in international locations outdoors of sub-Saharan Africa, the place baseline generic shares are decrease and might profit extra from market-based licensing.
I additionally discovered that the MPP generated optimistic spillover results for innovation. Corporations outdoors the pool elevated the variety of trials they performed on drug cocktails that included MPP compounds, whereas branded drug corporations collaborating within the pool shifted their focus to creating new compounds. This implies that the MPP allowed corporations outdoors the pool to discover new and higher methods to make use of MPP medication, akin to in new research populations or completely different remedy combos, whereas model identify corporations collaborating within the pool might spend extra assets to develop new medication.
The MPP was additionally in a position to reduce the burden of post-market surveillance for branded corporations, permitting them to push new medication by way of medical trials whereas generic and different impartial corporations might monitor the security and efficacy of accepted medication extra cheaply.
Total, my evaluation reveals the MPP successfully expanded generic entry to HIV medication in creating international locations with out diminishing innovation incentives. In actual fact, it even spurred corporations to make higher use of present medication.
Expertise licensing for COVID-19 and past
Since Might 2020, the Medicines Patent Pool has change into a key companion of the World Well being Group COVID-19 Expertise Entry Pool, which works to spur equitable and reasonably priced entry to COVID-19 well being merchandise globally. The MPP has not solely made licensing for COVID-19 well being merchandise extra accessible to low- and middle-income international locations, but in addition helped set up an mRNA vaccine expertise switch hub in South Africa to offer the technological coaching wanted to develop and promote merchandise treating COVID-19 and past.
Licensing COVID-19-related applied sciences may be sophisticated by the big quantity of commerce secrets and techniques concerned in producing medication derived from organic sources. These usually require further expertise switch past patents, akin to manufacturing particulars. The MPP has additionally labored to speak with model corporations, generic producers and public well being businesses in low- and middle-income international locations to shut the licensing data hole.
Questions stay on easy methods to greatest use licensing establishments just like the MPP to extend generic drug entry with out hampering the motivation to innovate. However the MPP is proving that it’s potential to align the pursuits of Huge Pharma and generic producers to avoid wasting extra lives in creating international locations. In October 2022, the MPP signed a licensing settlement with Novartis for the leukemia drug nilotinib – the primary time a most cancers drug has come below a public health-oriented licensing settlement.
