A Simple Invention to Help Women’s Health

BBC News reports the story of Arunachalam Muruganantham, a school dropout in rural India who invented a technology that could vastly improve reproductive health for women. The user-friendly technology relies on simple machines to produce sanitary pads at a low cost, a boon for women unwilling or unable to pay for the higher-priced sanitary pads in stores.

[Muruganantham] discovered that hardly any women in the surrounding villages used sanitary pads – fewer than one in 10. His findings were echoed by a 2011 survey by AC Nielsen, commissioned by the Indian government, which found that only 12% of women across India use sanitary pads.

Muruganantham says that in rural areas, the take-up is far less than that. He was shocked to learn that women don’t just use old rags, but other unhygienic substances such as sand, sawdust, leaves and even ash.

Women who do use cloths are often too embarrassed to dry them in the sun, which means they don’t get disinfected. Approximately 70% of all reproductive diseases in India are caused by poor menstrual hygiene – it can also affect maternal mortality.


Will First-to-File Hurt Small Inventors?

The U.S. just passed the first major patent reform in nearly sixty years – which includes as a central provision a change to the patent priority rule. Instead of awarding a patent to the first person to invent, we will join other nations in awarding patents to the first person to file an invention.
David Abrams and Polk Wagner have a great paper looking at whether the proposed change in our patent system from a “first to invent” regime to a “first to file” regime is likely to disadvantage individual inventors. The concern is that corporate inventors will have an easier time than the individual in gearing up to draft and file a patent application.
The paper ingeniously looks to see what happened when Canada introduced a similar reform in 1989. The paper is also a great way to teach yourself about the difference-in-difference approach to estimation. The paper first estimates the pre-reform difference between the U.S. and Canada in the proportion of patents going to individual inventors. It then looks to see whether this difference changed – that is, whether there was a difference in the difference – after the Canadian first-to-file reform went into effect.
