Dependent claims in patent applications must meet specific requirements as outlined in MPEP 608.01(i) : They must refer back to and further limit another claim or claims. They must include all limitations of the claim to which they refer. They must be more specific than the claim upon which they depend. The MPEP states: ‘A claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed.’ This ensures that dependent claims properly narrow the scope of the invention and provide additional protection for specific embodiments.
