Yes. If not mistaken, you can get a payed subscription allowing you to download the data. You can find information here.

This is more a comment than an answer, but it did not fit in the comment space.

Pathways, whether from KEGG or from anywhere else, are in the end not more than a construct that helps us to understand the relationships between a larger number of interactions. These individual interactions, and often their relationships should also be described in the literature (including online publications, blogs and published datasets, so it is more about previously published knowledge). If that is not the case an interaction should not be in a pathway.

I think that means that while pathways as a whole and (especially the format and the layout) can indeed be copyrighted the individual interactions can not, fall under that same copyright. Even is someone has a patent on an interaction (or a gene) that patent will normally not prevent you from using knowledge about it (although it might be wise to mention the patent).

Since many of us would prefer to have freely available pathways, not just to save the money, but also to be able to improve them with the strength of a community effort, I would strongly advocate to do just that. Initiatives like [?]WikiPathways[?] allow you to create new pathways or to extend existing ones and use those for for instance over representation analysis. If you find specific information that you think should be present in such freely available pathways and the basis of that information is available in published literature please add it. But please be careful before you copy larger chunks of formatted pathways. That might indeed be copyrighted or fall under licenses.

Disclosure: I am one of the authors of the papers about WikiPathways and [?]PathVisio[?] [[?]1[?], [?] 2[?], [?] 3[?]]. Those papers were written based on the same philosophy described here. But it means I do have an interest in WikiPathways being successful.

The license is quite specific:

Whatever your opinion of KEGG's decision to change their data licensing model, I would strongly encourage you not to break the terms of their license.

I am not certain whether the new terms of use cover versions of KEGG from before the paywall came down. I do know the webservices & API are still free.
