Why not merging multiple patents to save money?
I often find single company, single inventor submitted multiple patents at the same time. We all know that, to apply for a patent companies need to spend money. Now, at the first place why multiple patents of the same companies are not merged together to save money as there are no limits of claims for a patent (correct me if I am wrong). If multiple patents claims can be merged together without loosing information than it surely can reduce loads of patenting cost. Moreover, there is no disadvantageous point in legal perspective as claims are being merged without loosing information (from the state when they were separated).
How do the authority distinguish between two inventions or two claims? lets say, we have two inventions. 1. method of improving smartwatches battery, 2. method of improving smartwatches memory. Now if I merge both methods and presents in a way like 3. method of improving smartwatch ... on what ground the authority will reject? Where is the boundary?
