The Indian Supreme Court has rejected a patent for a slightly modified drug, on the basis that it was not a significant change.

The drug companies do this all the time, in order to extend their patents on drugs nearly indefinitely:

People in developing countries worldwide will continue to have access to low-cost copycat versions of drugs for diseases like H.I.V. and cancer, at least for a while.

Production of the generic drugs in India, the world’s biggest provider of cheap medicines, was ensured on Monday in a ruling by the Indian Supreme Court.

The debate over global drug pricing is one of the most contentious issues between developed countries and the developing world. While poorer nations maintain they have a moral obligation to make cheaper, generic drugs available to their populations — by limiting patents in some cases — the brand name pharmaceutical companies contend the profits they reap are essential to their ability to develop and manufacture innovative medicines.

Specifically, the decision allows Indian makers of generic drugs to continue making copycat versions of the drug Gleevec, which is made by Novartis. It is spelled Glivec in Europe and elsewhere. The drug provides such effective treatment for some forms of leukemia that the Food and Drug Administration approved the medicine in the United States in 2001 in record time. The ruling will also help India maintain its role as the world’s most important provider of inexpensive medicines, which is critical in the global fight against deadly diseases. Gleevec, for example, can cost as much as $70,000 a year, while Indian generic versions cost about $2,500 a year.

The ruling comes at a challenging time for the pharmaceutical industry, which is increasingly looking to emerging markets to compensate for lackluster drug sales in the United States and Europe. At the same time, it is facing other challenges to its patent protections in countries like Argentina, the Philippines, Thailand and Brazil.

“I think other countries will now be looking at India and saying, ‘Well, hold on a minute — India stuck to its guns,’ ” said Tahir Amin, a director of the Initiative for Medicines, Access and Knowledge, a group based in New York that works on patent cases to foster access to drugs.

In Monday’s decision, India’s Supreme Court ruled that the patent that Novartis sought for Gleevec did not represent a true invention. The ruling is something of an anomaly. Passed under international pressure, India’s 2005 patent law for the first time allowed for patents on medicines, but only for drugs discovered after 1995. In 1993, Novartis patented a version of Gleevec that it later abandoned in development, but the Indian judges ruled that the early and later versions were not different enough for the later one to merit a separate patent.

Leena Menghaney, a patient advocate at Doctors Without Borders, said that the ruling was a reprieve from more expensive medicines, but only for a while.

“The great thing about this ruling is that we don’t have to worry about the drugs we’re currently using,” Ms. Menghaney said. “But the million-dollar question is what is going to happen for new drugs that have not yet come out.”

Others decried the ruling, saying it was further evidence that India does not respect the intellectual property rights of pharmaceutical companies. Last year, India granted what is known as a compulsory license to a generic drug manufacturer to begin making copies of Bayer’s cancer drug Nexavar, and revoked Pfizer’s patent for another cancer drug, Sutent. Both companies have appealed the decisions.

First, evergreening does not serve to create new products, it encourages minor, non-functional, changes to existing products to maintain a monopoly.

Second, compulsory licensing is specifically allowed for under all major international IP and trade regimes.

Unfortunately, when you look at intellectual protections (IP) as property it means that the holder of that monopoly has a God given right to extract unreasonable rents forever.

There is no place where our patent system is more broken than in the evergreening of pharmceuticals, and that is saying a lot.
