According to DigiTimes, HTC is insisting that its works are original and not a copy of Apple’s products, designs, or efforts:

HTC insisted that it designed and developed its user interface, the HTC Sense, in-house, and with the same spirit, it has rolled out a number of innovative smartphones over the past 13 year. HTC launched its HTC Sense touch-enable user interface in June 2009.

HTC also stated it believes that the patent complaint is unlikely to result in a significant impact on its operations in the near team, or affect its business guidance for the first quarter of 2010.
