This article describes the patent application "of the independent claims" writing method.
Item claims in claim 1 is claimed in the independent claims, to reflect the Utility Model technical solution as a whole, according to essential features to solve the problem, it must be the root to determine the scope of patent protection. In a patent application, there are usually a number of patents in claim 1 wherein the first item is the independent patent claim, the remainder is generally dependent patent claims. In a patent application, if it is the only one of the independent claims as claimed in claim.
In the independent claims, the preamble of Claim is made of part of the requirements and characteristics. Boundary is "characterized in that" or "characterized by." Prior to the preamble, it is characterized after this section.
The preamble of the first to specify the name of the present inventions, then stated prior art to the present invention is to create a common technical features.
Stated technical features of the characterizing part of the present invention to create unique. These features and technical features of the preamble of claim together constitute inventions achieve complete aspect purpose, i.e. the scope of the claims.
Example:
1. A pressure cooker comprising a lid, the control valve, and a handle pot, characterized in that a safety valve provided on said lid, said bottom of the outer pot is provided with an electric heater.
2. A test pencil, in the insulating housing, the test contacts, the current limiting resistor, a neon tube and hand contact electrode connected sequentially, characterized in that the test contacts with a shunt resistor connected to one end, the other end of the shunt resistor identifying electrode connected to the human body may be in contact.
3. A host interface bus M-Bus device, comprising M-Bus bus master transmission circuit and the reception circuit, characterized in that said transmission circuit comprises a N-channel MOS transistor and P-channel MOS pipe connected thereto; the receiving circuit includes an operational amplifier and optocoupler connected thereto.
4. A host sends MBUS-end circuit, characterized in that: the other end of the power source voltage input terminal of the chip, the bus MBUS output end, the end opposite the terminating I regulator circuit, the regulator circuit I II regulator circuit and a control end of the switch at one end, the other end of the control voltage regulator circuit II, and the other terminal of the switch, the control terminal controlling serial switch TX.
