Is it legal to sell a serial number on eBay

I cannot give legal advice on the web, but I can identify some issues you may wish to consider. This is an intellectual property question that many attorneys may be able to address. The Wisconsin Bar Association offers a Lawyer Information and Referral Service. You may be able to get a reduced fee consultation through their website.

1. Most computer programs have licenses that tell you how you are authorized to use the software. When you purchase the program, you are really purchasing a license. Each license is different. Only an attorney can tell you if resale after use is within your license.

2. The situation might be different if you had not opened the box. Many software programs have licensed that only take effect when you open the envelope containing the software CD or whatever media the program is contained on.

3. I will reveal technological ignorance by telling you that I don't know if there is something within the program that recognizes a unique "serial number" or if it screens serial numbers for certain patterns. However, if a serial number might be used with numerous programs, you should consult an attorney to see if selling the serial number separately from the program will create problems.

4. Unfortunately, culture, technology and law are in disagreement over the use, sharing and sale of software, music and videos/films. As an attorney, I must tell you that there are severe penalties for illegal use of intellectual property, including triple damages and, depending on the circumstances, attorney fees.
