昨天收到一个欧洲大客户的邮件,在他表明对我们公司产品光效的赞叹后,又提到了芯片专利问题,原文是:From looking at your spectral data, I am afraid that your LED lamps have YAG phosphor and this is only legal in case you have a patent license agreement from Nichia of Japan. Can you confirm whether or not your lamps contain YAG, and if yes, do you have the license agreement from Nichia? If not, can you use other legal phosphors such as LuAG or BaSrSiOx? 这邮件是对方研发部经理发的,他怀疑我们芯片专利问题.我们的芯片是晶能和清华同方,之所以高光效是因为独创的封装方式。面对这样专业客户该怎么引导才好,各位大师,指点迷津
