                                                                   A Lucky Thing

     About sixty years ago, a child named Borty was playing one day with a group of naughty boys. When

they were playing happily, an incident happened. An elder child picked up Borty and threw him into the sky.

When Borty fell down, the big child did not catch him but rather let him fall on the ground. As a result, Borty's

leg broke.

     He had to wear heavy plaster while lying in bed for several months. The worst thing was that his leg bone

did not heal. It was a terrible thing to a little child. Little Borty screamed in pain and fear.

     This was a tragedy, but now Borty had a new idea that he was now one of the most famous writers in

the world. Maybe you are not familiar with the name of Borty, But when I mention the name Wells, you must

know it. Maybe you have read some books of his. He wrote more than 75 books. Wells thought that breaking

his leg was a lucky thing for him. It made him have to stay home for one year. In the year he read many books,

because he had nothing to do except that. It made him very interested in literature. He became enlightened by

these books. So his staying home was a turning point for him. Later he became the writer in the world whose

income was highest.

（2005年） 　　三、（本题18分） 　　案情：甲公司指派员工唐某从事新型灯具的研制开发，唐某于1999年3月完成了一种新型灯具的开发。甲公司对该灯具的技术采取了保密措施，并于2000年5月19日申请发明专利。2001年12月1日，国家专利局公布该发明专利申请，并于2002年8月9日授予甲公司专利权。此前，甲公司与乙公司于2000年7月签订专利实施许可合同，约定乙公司使用该灯具专利技术4年，每年许可使用费10万元。 　　2004年3月，甲公司欲以80万元将该专利技术转让给丙公司。唐某、乙公司也想以同等条件购买该专利技术。最终甲公司将该专利出让给了唐某。唐某购得专利后，拟以该灯具专利作价80万元作为出资，设立一家注册资本为300万元的有限责任公司。 　　2004年12月，有人向专利复审委员会申请宣告该专利无效，理由是丁公司已于1999年12月20日开始生产相同的灯具并在市场上销售，该发明不具有新颖性。经查，丁公司在获悉甲公司开发出新型灯具后，以不正当手段获取了甲公司的有关技术资料并一直在生产、销售该新型灯具。 　　问题：

对丁公司的违法行为应如何定性？为什么？
