Chapter 200
Chapter 200 covers the different types of patent applications and how to claim benefit of earlier filing dates. It addresses continuation, divisional, and continuation-in-part applications, provisional applications, and foreign priority claims. Key rule: CIP adds new matter, continuation and divisional do not.
Core Concepts
Application Types — MPEP 201 Nonprovisional: full application entitled to a filing date and examination. Provisional: placeholder — 12 months to file nonprovisional claiming benefit, no examination, no claims required. Reissue: corrects defective issued patent. Divisional: restriction requirement triggered, claims distinct invention. Continuation: same disclosure, new claims. CIP: adds new matter — new matter only gets filing date of CIP, not parent.
Continuation vs. CIP — MPEP 201.07/201.08 Continuation: same invention, same disclosure as parent, claims benefit of parent filing date for ALL claims. CIP: adds new matter — claims directed to new matter only get CIP filing date. Critical exam distinction: if claim relies on new matter, parent filing date does NOT apply.
Provisional Application — MPEP 201.04 Cannot claim priority to another application. No examination, no claims required. Must file nonprovisional within 12 months or benefit is lost. 12-month period is not extendable. Provisional establishes earlier filing date only if nonprovisional discloses same invention.
Benefit Claims — 35 USC 120 / MPEP 211 Requirements: (1) copendency — later app filed before earlier app abandons; (2) specific reference to prior app in ADS; (3) at least one inventor named in the later app must also be named in the prior app; (4) disclosure supports claims (written description). Reference must be in ADS for apps filed on or after September 16, 2012.
Foreign Priority — 35 USC 119(a) / MPEP 213 Must file U.S. nonprovisional within 12 months of foreign filing (6 months for design). Must claim priority in ADS and file certified copy. Right of priority does not add subject matter — only establishes earlier date. Paris Convention controls recognized countries.
Status of Applications — MPEP 203 New: no examiner action yet. Rejected: unanswered Office Action pending. Amended: applicant replied to examiner action. Allowed/In Issue: notice of allowance sent. Abandoned: removed from docket — failure to reply, failure to pay issue fee, or formal abandonment.
Key Rules
EXAM TIP
Two most tested distinctions: (1) CIP vs continuation — if new matter is added, the claims covering new matter only get the CIP filing date, not the parent date. This affects prior art analysis significantly. (2) Copendency requirement for benefit claims under 35 USC 120 — if the parent abandons before the continuation is filed, the benefit claim is lost entirely.
