Critical Time Periods — Complete Reference

Utility Patent term:          20 years from earliest effective filing date (35 USC § 154)
Trademark term:               10 years from registration (Lanham Act § 8/9 renewals)
Design patent term:           15 years from grant (AIA, post-May 13, 2015)
Utility model term:           10 years from filing (foreign systems)

AIA Grace Period:             12 months before filing date (35 USC § 102(b)(1))
USPTO Office Action Response: 3 months (extendable to 6 months with fee)
Publication of application:   18 months from earliest filing date (35 USC § 122(b))
Paris Convention priority:    12 months (patents/utility models); 6 months (TM/design)
PCT national phase entry:     30 months from priority date (Rule 39 PCT)
Trademark non-use abandonment: 3 consecutive years (15 USC § 1127)
US provisional application:   12-month pendency before conversion to non-provisional

Top 10 High-Frequency Exam Errors

① Utility patent = 20 yrs from FILING (not from grant)
② Design patent = 15 yrs from GRANT (not from filing)
③ Trademark = 10 yrs from REGISTRATION + unlimited renewal
④ AIA grace period = 12 months before FILING (inventor's own disclosure)
⑤ Patent invalidity = retroactive effect (never existed)
⑥ Trademark non-use abandonment = 3 consecutive years
⑦ AIA = first-inventor-to-file (since March 16, 2013)
⑧ PCT national phase entry = 30 months from priority date
⑨ Paris Convention priority = 12 months (6 months for TM/design)
⑩ Copyright = arises automatically at creation; no registration required for protection

Key Concept Cards

Four IP Categories = Utility Patent · Utility Model · Trademark · Design Patent ★★★★★ : Know subject matter, term, and examination type for each. Memory hook: invent · improve · brand · look

Patent Requirements = Novel + Non-Obvious + Useful ★★★★★ : 35 USC §§ 101, 102, 103 — the three pillars of patentability. Memory hook: NNU (new · not obvious · useful)

PCT = 30-Month National Phase Deadline ★★★★★ : Distinct from Paris Convention 12-month priority window. Memory hook: PCT = 30 months

Practice Questions (Comprehensive)

Q. What is the first step in building a patent strategy for a startup?

(1) Prior art search: use USPTO Patent Full-Text and Image Database (PatFT/AppFT) and Google Patents to assess patentability. (2) Trade secret vs. patent decision: if the invention is easily reverse-engineered, file a patent; if secrecy is maintainable, consider trade secret. (3) File a provisional application immediately to secure a priority date at relatively low cost (~$320 micro-entity fee). (4) Evaluate PCT filing if international expansion is planned. (5) Work with a registered patent practitioner (attorney or agent) to draft claims — the claims define what competitors cannot do. (6) Budget constraints: prioritize the 1–2 core claims that protect your core value proposition.

Q. Why does the USPTO Patent Bar Exam require a technical background?

Patent practitioners represent inventors in USPTO proceedings — without understanding the technology, a practitioner cannot draft claims that accurately capture the invention, respond effectively to technical rejections, or distinguish the invention from prior art. In prosecution, Office Actions often involve highly technical arguments. In disputes, claim construction turns on the meaning of technical terms. The USPTO therefore requires registrants to hold a qualifying science or engineering degree (or equivalent technical experience). This science + law combination is the patent practitioner’s core competency.
