patent right granted was revoked = “Method for monitoring a Sensor”-” The Wind Turbine Components and Operation”=The applicant seeks revocation of the Patent No: 203552 for an Invention titled” Method for monitoring a Sensor.”= from the 1990s in India and elsewhere in the world there has been a spurt in wind energy activity. The 1990s were undoubtedly years of considerable change. The rated capacity of wind turbines was increasing rapidly, as was the size of wind farms. Wind speed cannot be controlled. It increases or decreases at will. That is why prediction of the wind speed and monitoring is required. We have already seen that ‘041 tells us that the blade pitch angle was known to be one of the parameters. If the pitch angle is not variable, then of course the anemometer can not use it to monitor the wind flow, But if the pitch angle can be varied and the wind speed is very high , what will the person skilled in the art who has common sense do? She will use the other known parameter that is the blade pitch angle and feather the blades. The answer it appears “is blowing’ in the wind”, it is obvious. 52. The proposed claim also speaks of detecting the flow speed, comparing it with at least one operating parameter and of the sequence the parameters. -Further all the features of the proposed claims are obvious as seen above. In the result, the patent No.IN203552 is revoked.
