Pre-infringement
Contracts
Contracts are a pre-infringement control method, which very often is underestimated. Properly formed contracts enable copyright holders to restrict the use of their works in excess of the rights granted under copyright laws.
Copy Protection
This approach was standard in the 1980s, but rejected by consumers and relatively easy to break. Still copy protection, whereby the vendor limits the number of times a file can be copied, is used in certain situations.
Limited Functionality
This method allows copyright owners to provide a copy of the work, which is functionally limited. Software creators, for example, can distribute software that cannot print or save. A fully functional version has to be bought from the vendor.
Date Bombs
Here the intellectual property holder distributes a fully functional copy but locks off access at a pre-specified date or after a certain number of uses.
