Paper M2 common mistakes

Paper M2 · Understand the traps and how to avoid them.

Mistake 1

Call a PCT application a worldwide granted patent

The international route does not itself grant all territorial rights.

What to do instead

Track the actual phase, office and later grant status.

Mistake 2

Assume a priority claim is always valid

Entitlement and subject-matter conditions still apply.

What to do instead

Assess priority for the actual filing and claimed subject matter.

Mistake 3

Treat narrowing as automatic amendment support

A narrower combination may add undisclosed subject matter.

What to do instead

Check the application as filed under the applicable disclosure standard.

Mistake 4

Add nested periods without checking their trigger

Different periods may run from the same event.

What to do instead

Record the legal rule and triggering date for each period.

Mistake 5

Treat every missed step as further-processing eligible

Available remedies have specific exclusions and conditions.

What to do instead

Identify the actual omission and permitted route.

Mistake 6

Use review as a general extra appeal

A petition for review has limited grounds.

What to do instead

Distinguish the prescribed procedural review from substantive disagreement.

Mistake 7

Mark a draft as filed

Preparation does not establish office receipt.

What to do instead

Verify the actual submission record and preserve evidence.

Mistake 8

Treat EPAC and EQE as the same qualification

Administration certification and professional qualification have distinct roles.

What to do instead

Use the intended current assessment and professional framework.
