With increasing advances in medical biotechnology, dressing on the wound, the gauze has been different from the traditional, high-end biological dressings seem to be a priority for today's. In addition, moist wound healing has also become the future treatment and care of major trauma trend, creating moist wound environment to promote faster healing, reduced risk of infection, reduce scar formation and reduce the cost of care is a basic condition for advanced dressings. Moist dressings accounted for 45% of market value and 6% annual rate of increase, with a bright future. L Company solutions to moist wound healing as the main trend of future treatment and wound care, and the efficiently absorb exudate, high biocompatibility, antibacterial and medicated water effect are the future moist dressings competitive core of key commodities. The high efficiency and easy operation characteristics, particularly for wound care applications, postoperative wound care and pressure sores caused by aging, the diabetic foot, venous ulcers and other wound care market has a key influence. This purpose of this study is using lean innovation development process to strengthen the patent portfolio, patent exploration by analysis, and then find out the status of some patents held by each dressing manufacturers in the world at present, to further evaluate the technology gap L company R&D and market development policy, through efficient when conducting a patent search will be more effective research and innovation.
