The standards required for patentability are quite different from scientific novelty or interest. Paying reviewers is not a bad idea, as journals that pay will both be more likely to attract quality reviewers, and it also creates a contract between the reviewer and the journal. Such a contract could include requirements for the standard of reviewing. If a paper is later found to have been poorly reviewed the journal can seek redress from the reviewers, further encouraging them to do their job properly.
