Q10. Claim Format
 Is one particular claim format, for example, European two-part form, Jepson, etc., affect a scope of protection in later stage, such as litigation? If yes, what format is advantageous/disadvantageous?

A10. No, claim format does not affect a scope of protection.
 In some countries, a preamble in a two part form claim or a Jepson type claim is interpreted as a prior art. In Japan, every technical features in a claim, including a preamble and a body, are treated equally and a scope of protection is interpreted from whole written technical features in a claim. Therefore, there is no particular claim format which is advantageous/disadvantageous.
