That would be merely speculation. As Terje Tvedt has demonstrated, it doesn't matter if they whole world had a superior patent system. The industrial revolution simply could not have happened elsewhere. The water situation simply did not allow it.

All the key inventions that drove the British industrial revolution mostly existed elsewhere, such as China and Italy. Sometimes hundreds of years before Britain. Patents or no patents. The key difference is that they did not have the landscape and climate which allowed transportation and water power at the massive scale possible in the UK combined with rich supply or iron and coal close to major waterways.
