Thanks for your post. To respond to your points:

1. You can download structures right now. Under every structure in ChemSpider there are a number of options, one of which is to Save [the structure] as a mol file. If you click on this you can download the file to open in your favorite chemical structure editor. Depending on how you configure your web browser you can probably even get the browser to open your structure editor when you click on the Save button. for example, in Firefox I get asked if I want to save or open the file when I click on the Save button.

2. As far as downloading the database goes – we don’t believe that this is a practical or useful thing for most users to do. The database has over 26 million entries and new compounds, spectra and links are added every day, and hundreds of curations are performed weekly. In the modern world static databases that are out of date as soon as they are downloaded don’t seem like the best tool.
Where businesses are worried about IP protection we would suggest that they email us directly so that we can discuss their concerns, and look at ways of providing solutions tailored to their needs.
