Biomedical innovation reached a brand new period through the COVID-19 pandemic as drug improvement went into overdrive. But the ways in which model firms license their patented medicine grant them market monopoly, stopping different entities from making generics to allow them to solely revenue. This considerably limits the attain of lifesaving medicine, particularly to low- and middle-income nations, or LMICs.
I’m an economist who research innovation and digitization in well being care markets. Growing up in a growing 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 pays one low worth for permission to make and distribute all of the remedies coated by the pool. My current 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 firms.
Patent swimming pools may help improve entry to costly medicine.
Drug patents within the international panorama
Patents are designed to supply incentives for innovation by granting monopoly energy to patent holders for a time frame, sometimes 20 years from the appliance submitting date.
However, this intention is difficult by strategic patenting. For instance, firms can delay the creation of generic variations of a drug by acquiring extra patents primarily based on slight modifications to its formulation or technique of use, amongst different techniques. This “evergreens” the corporate’s patent portfolio with out requiring substantial new investments in analysis and improvement.
Furthermore, as a result of patents are jurisdiction-specific, patent rights granted within the U.S. don’t mechanically apply to different nations. Firms typically acquire a number of patents masking the identical drug in several nations, adapting claims primarily based on what’s patentable in every jurisdiction.
To incentivize know-how switch to low- and middle-income nations, member nations of the World Trade Organization signed the 1995 Agreement on Trade-Related Aspects of Intellectual Property Rights, or TRIPS, which set the minimal requirements for mental property regulation. Under TRIPS, governments and generic drug producers in low- and middle-income nations might infringe on or invalidate patents to convey down patented drug costs beneath sure circumstances. Patents in LMICs have been additionally strengthened to incentivize corporations from high-income nations to speculate and commerce with LMICs.
Determining what’s patentable may be difficult.
The 2001 Doha Declaration clarified the scope of TRIPS, emphasizing that patent laws mustn’t stop 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 apply after TRIPS is Novartis’ anticancer drug imatinib (Glivec or Gleevec). In 2013, India’s Supreme Court denied Novartis’s patent software for Glivec for obviousness, which means each consultants or most of the people might arrive on the invention themselves with out requiring a lot talent or thought. The subject centered on whether or not new types of identified substances, on this case a crystalline type of imatinib, have been too apparent to be patentable. At the time, Glivec had already been patented in 40 different nations. As a results of India’s landmark ruling, the worth 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
Although TRIPS seeks to steadiness incentives for innovation with entry to patented applied sciences, points with patents nonetheless stay. Drug cocktails, for instance, can comprise a number of patented compounds, every of which may be owned by totally different firms. Overlapping patent rights can create a “patent thicket” that blocks commercialization. Treatments for power circumstances that require a steady and cheap provide of generics additionally pose a problem, as the fee burden of long-term use of patented medicine is usually unaffordable for sufferers in low- and middle-income nations.
One answer to those drug entry points is patent swimming pools. In distinction to the at the moment decentralized licensing market, the place every know-how proprietor negotiates individually with every potential licensee, a patent pool supplies a “one-stop store” the place licensees can get the rights for a number of patents on the identical time. This can 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 regularly disappeared after a 1945 U.S. Supreme Court determination that elevated regulatory scrutiny, hindering the formation of recent swimming pools. Patent swimming pools have been later revived within the Nineteen Nineties in response to licensing challenges within the info and communication know-how sector.
The Medicines Patent Pool
Despite many challenges, the primary patent pool created for the aim of selling public well being shaped in 2010 with assist from the United Nations and Unitaid. The Medicines Patent Pool, or MPP, goals to spur generic licensing for patented medicine that deal with ailments disproportionately affecting low- and middle-income nations. Initially masking solely HIV medicine, the MPP later expanded to incorporate hepatitis C and tuberculosis medicine, many medicines on the World Health Organization’s important medicines listing and, most lately, COVID-19 remedies and applied sciences.
But how a lot has the MPP improved drug entry?
I sought to reply this query by inspecting how the Medicines Patent Pool has affected generic drug distribution in low- and middle-income nations and biomedical analysis and improvement within the U.S. To analyze the MPP’s affect on increasing entry to generic medicine, I collected knowledge on drug licensing contracts, procurement, private and non-private patents and different financial variables from over 100 low- and middle-income nations. To analyze the MPP’s affect on pharmaceutical innovation, I examined knowledge on new scientific 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 medicine equipped to LMICs. Increases have been larger in nations the place medicine are patented and in nations 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 constructive spillover results for innovation. Firms outdoors the pool elevated the variety of trials they carried out on drug cocktails that included MPP compounds, whereas branded drug corporations taking part within the pool shifted their focus to growing new compounds. This means that the MPP allowed corporations outdoors the pool to discover new and higher methods to make use of MPP medicine, corresponding to in new examine populations or totally different remedy mixtures, whereas model identify corporations taking part within the pool might spend extra assets to develop new medicine.
The MPP was additionally in a position to reduce the burden of post-market surveillance for branded corporations, permitting them to push new medicine via scientific trials whereas generic and different impartial corporations might monitor the security and efficacy of permitted medicine extra cheaply.
Overall, my evaluation exhibits the MPP successfully expanded generic entry to HIV medicine in growing nations with out diminishing innovation incentives. In reality, it even spurred firms to make higher use of present medicine.
Technology licensing for COVID-19 and past
Since May 2020, the Medicines Patent Pool has develop into a key companion of the World Health Organization COVID-19 Technology Access 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 nations, but in addition helped set up an mRNA vaccine know-how switch hub in South Africa to supply the technological coaching wanted to develop and promote merchandise treating COVID-19 and past.
Licensing COVID-19-related applied sciences may be difficult by the massive quantity of commerce secrets and techniques concerned in producing medicine derived from organic sources. These typically require extra know-how switch past patents, corresponding to manufacturing particulars. The MPP has additionally labored to speak with model corporations, generic producers and public well being companies in low- and middle-income nations to shut the licensing data hole.
Questions stay on find out how to finest use licensing establishments just like the MPP to extend generic drug entry with out hampering the motivation to innovate. But the MPP is proving that it’s attainable to align the pursuits of Big Pharma and generic producers to save lots of extra lives in growing nations. 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 beneath a public health-oriented licensing settlement.
