Learn English – Usage of “even when”

meaningwhen

In my understanding, a sentence of the following form

A requires B, something that may be difficult even when C

means that

A is difficult since a necessary condition B is difficult. While B appears to be easier (to obtain or achieve) in the case of C, it is indeed not.

However, I came across the following sentence in a law paper
(Lemley, M. A. (2007). Ten things to do about patent holdup of standards (and one not to). BCL Rev., 48, 149.):

… proving an antitrust violation requires detailed evidence of both causation and intent, something that may be difficult even when, as a policy matter, a patentee should not be permitted to extend its rights.

I don't understand the latter part of the sentence.
Could you please help me to clarify the meaning of the sentence. Thank you.

(a little context: a patentee can violate antitrust laws if it abuses its patent rights)

'even when' is used to make explicit an included situation that might be thought of as an exception. So:

  • "A soldier must obey all orders, even when he disagrees with them"
  • "The accused is entitled to a fair trial, even when he seems obviously guilty"

The sentence you quote admits of two slightly different meaning. Exactly as written, it should mean:

"proving an antitrust violation requires detailed evidence of both causation and intent. This is difficult, regardless of whether a patentee should not be permitted to extend its rights, which you might think would make it easier."

But I believe the intended meaning is:

"proving an antitrust violation requires detailed evidence of both causation and intent, and this is difficult. But it is required, regardless of whether a patentee should not be permitted to extend its rights, which you might think should make it not required."

My personal belief is that a comma after 'difficult' would make it clearer.
