Our attempt at e-EQE Paper A 2021 - Coated engine components

Here is our quick first attempt at the claims (ignoring formal aspects).

We note that this claim set has two independent claims drawn to a method of manufacturing the claimed product. We considered including the (e-beam and plasma spraying) methods described by the client in a single claim, but decided to err on the safe side and claim both methods separately.

We welcome your comments. (Click "Read more" to see all 15 claims and all comments)

The paper and our answers

Copies of the paper will be provided on this blog as soon as we have received copies of the papers, preferably in all three languages (English, French and German). Should you have a copy, please send it to any of our tutors or to training@deltapatents.com.

The core of our answers will be given as soon as possible in a separate blog post.

We look forward to your comments!

Comments are welcome in any official EPO language, not just English. So, comments in German and French are also very welcome!

Please do not post your comments anonymously - it is allowed, but it makes responding more difficult and rather clumsy ("Dear Mr/Mrs/Ms Anonymous of 04-03-2021 23:24"), whereas using your real name or a nick nameis more personal, more interesting and makes a more attractive conversation. You do not need to log in or make an account - it is OK to just put your (nick) name at the end of your post.

Please post your comments as to first impressions and general remarks to this blog.
Please post responses to our answer (as soon as available) to the separate blog post with our answer.
Thanks!
