CharingX™ Purpose-built AI platform for patent practitioners, by patent practitioners

A founder’s story

Some people take up golf. He bought GPUs.

It began, as these things do, with an irritation that wouldn’t go away. As a patent attorney, he spends his days putting his name on sophisticated arguments that have to be exactly right, down to the comma. The new AI tools were fast and impressive, and he wanted them to help. But he couldn’t see inside them, couldn’t vouch for what they produced, and wasn’t about to hand his clients’ secrets to a stranger’s server to find out.

Most lawyers would have shrugged and gone back to the old way. Rakesh had been an engineer long before he was an attorney, and engineers have a reflex for this: if nobody makes the thing you need, you build it. The entrepreneur in him did the rest.

So the boxes started arriving. GPUs. Power supplies the size of carry-on luggage. Processors no reasonable person needs. Pumps, radiators, and tubing for liquid cooling, because those GPUs run hot enough to cook breakfast. He put the machines together from bare metal, one cable at a time, and set about writing the code and libraries to teach them to work the way a careful practitioner works.

The first version set out to fix one small, stubborn thing: AI work that he couldn’t verify and that lacked the depth this practice demands. But for a mind that can’t walk past a crooked picture, straightening one frame only shows how off-plumb the wall is. So the wall came out. Then the room. Before long he was reframing the whole house, so that everything in it would stand exactly upright.

The real place, meanwhile, got extra air conditioning, just to keep those hot monsters cool. Really.

That’s how CharingX came about. Not from a pitch deck, not for jumping on the AI bandwagon, but from a practitioner who wanted to trust what he signed, and an engineer who couldn’t leave a problem alone. They turned out to be the same person, building away into the small hours in that flat on the seventh floor.

What's in the name?

The name

CharingX began on Charing Cross Road in London. The name is a nod to the city's mile zero at Charing Cross, and to the booksellers who still line the road.

The mark

Seven books on a curved shelf, and one light still on, seven floors up.
