发明日在美国专利法上意义重大。朋友们在这儿搞研发，都有良好的研发习惯，对发明从脑子一闪念，横空出世，到其后的发展，完善，论证，测试，检验，上下左右间的交流，着手准备专利申请等等都会做详细的记录，以备将来证明你的发明日之需。在中国，除了证明发明人资格时有点用处外，发明日的意义不大，对它的重视也就不太够。所以，你要海归，就很有可能多少丢掉一些这儿养成的良好研发习惯。如果你海龟后，从此与美国一刀两断，永不申请美国专利，这些习惯丢就丢了。否则，你最好别丢。中国过去不是世界贸易组织WTO成员国，所以美国那时候是不承认中国的这些发明证据的。中国加入WTO后，美国才开始承认。所以，不管谁在中国搞发明，养成或保持好的研发习惯，都是有益无害的。欲精确理解在美国之外有关确立发明日的规定，请参下段。
