Can I include a "method and apparatus claim" for a patent filed in the UK? I'm developing a system that uses augmented reality in novel ways. All the patent prior art that I can find involves method claims and apparatus claims. But I've read that in the UK you can't patent business methods or software. So if I include a apparatus claim and a method claim in my application, would the method claim be ignored? or would that application be rejected?

If before 12 months after filing my UK patent, I file a patent application in the US claiming priority to my UK filing date, would then I be able to use the method claim even if in the UK application was rejected? would I, at this point, be able to change the claims for the US application, provided the specification supports these new claims?

As the second part of your question's been answered, I'll just answer the first part. Yes, both method and apparatus claims are both permissible for UK patents. Sometimes I write 'system' claims that are a bit of both!

You are also correct that methods of doing business, and programs for computers are both excluded - insofar as the invention relates to those things as such. The 'as such' is important - technical advances that happen to be implemented by software, and used in a business method, may still be patentable. The criterion is whether the contribution itself is solely in the excluded areas. The formal structure of the claim - method, apparatus, or whatever, is not important.

The leading case (at the moment!) is Aerotel/Macrossan, which provides a structured set of questions. There's also some practical guidance in the AT&T Knowledge Ventures case, called the AT&T signposts. The first chapter of the UK IPO patent manual http://www.ipo.gov.uk/practice-sec-001.pdf discusses all this.

It's easier appreciate after looking at some examples, rather than discussing it in the abstract. I'd recommend looking at some UK IPO decisions http://www.ipo.gov.uk/pro-types/pro-patent/pro-p-os/p-challenge-decision-results.htm . Go to the 'keyword or phrase' and filter by 'excluded field (allowed)' or 'excluded field (refused)' and have a look through the decisions.

What you include in the claim - and the description as a whole - can really make a difference. Emphasise the non-excluded technical aspects using the AT&T guidance.

It's worth noting that the EPO use different criteria (though the underlying law is supposed to be the same). I'd say they're more lenient. After an EP patent is granted, you then validate it in your chosen European countries, which includes the UK; this would be more expensive than just going direct through the UK IPO (and of course if you try and enforce it in the UK courts, they'll apply the UK excluded matter tests, and might revoke the patent!). But as for the US application you are considering, you can file the EP application within 12 months of your initial UK application, claiming priority.

Very nice answer with good information and citations; thanks! –  Yorick Jan 28 '13 at 12:32
    
I've read the practice-sec-001.pdf you suggested. I have the subject more clear now. Thanks very much. –  martinako Jan 28 '13 at 12:54

For the second part of the question: Yes the U.S. application, under Article 4 of Paris Convention, would get priority from the U.K. application as-submitted regardless of the ultimate fate of the U.K. application.

Ok, thanks. Do you know if I would be able to change the claims when filing the US application -- provided is within the first 12 months of the priority date? –  martinako Jan 27 '13 at 0:04

In the U.S. you can cancel, add and amend the claims all you like - providing there is sufficient support in the application-as-filed for the amended and added claims. –  George White Jan 27 '13 at 0:18
    
fantastic, thanks. –  martinako Jan 27 '13 at 0:23
