The activation process increases the available surface area to carbon dramatically which is why it is useful for filtration. By the way, patent titles are not particularly relevant to what a patent protects. For that, you need to read the claims. For your question about reviving patents, it is a good one and I'd recommend posting it as a formal question. I think the answer is maybe, but I'm not a patent attorney so I can't say under what circumstances you can. | |
