The problem

Territoriality creates the problem cooperation solves

Recall from Lecture 1: an IP right is territorial. A patent granted in India confers no rights in the United States. Yet a computer science innovation is deployed globally on day one — so the mismatch between a territorial right and a borderless technology is structural, not incidental.

Before the conventions

An inventor exhibiting at an international exhibition risked losing novelty in every country they had not yet filed in. Foreign nationals were routinely discriminated against by domestic IP offices.

The industrial revolution as catalyst

Cross-border trade made divergent national regimes commercially intolerable. The 1873 Vienna Exposition is the usual marker: inventors refused to attend for fear of disclosure.

The three answers

Paris, 1883 — industrial property
Berne, 1886 — literary and artistic works
TRIPS, 1994 — everything, with teeth

What these treaties do and do not do

They establish national treatment, minimum standards and procedural mechanisms for filing across borders. They do not create a global IP right. Substantive patent law — what is patentable, how it is examined, how long it lasts — remains national.

CSEG3060 · Unit V · Lecture 3 — The International IP System3

Framework · 1 of 3

Paris 1883 — national treatment and the right of priority

Scope

Industrial property in the broadest sense: patents, utility models, industrial designs, trademarks, service marks, trade names, geographical indications, and the repression of unfair competition.

Signed 20 March 1883 by 11 states; over 180 contracting parties today.

Article 4 — the right of priority

Patents and utility models12 months
Industrial designs6 months
Trademarks6 months

File once at home, then have twelve months to decide on foreign filings without losing the original date. This single provision dramatically reduces cost and risk.

Article 2 — national treatment

Foreign nationals of any member state must receive the same protection as nationals of the country where protection is sought. No discrimination by nationality.

Article 4bis — independence

Patents in different member states are independent. Grant, scope or termination in one country does not affect status in another.

The limitation

Paris sets only broad principles and minimum standards. It provides no system of international registration or examination. That gap is what the PCT, 87 years later, was built to fill.

Worked example — a researcher at IIT Delhi files a provisional in India on 15 March 2025. On 10 February 2026, within the 12-month window, she files in the United States. The US application is treated, for novelty, as if filed on 15 March 2025 — excluding any prior art published between those dates.

CSEG3060 · Unit V · Lecture 3 — The International IP System4

Framework · 2 of 3

Berne 1886 — protection without formalities

Three core principles — Article 5

Automatic protection. Protection requires no registration, formality or deposit. Once a work is created and fixed in a tangible medium it is protected in all member states. This contrasts sharply with patent law.

National treatment. Works originating in one member state receive the same protection elsewhere as works of national origin.

Independence of protection. Protection abroad is independent of protection in the country of origin — a work in the public domain at home may still be protected elsewhere.

Minimum standards

Economic rights: translation (Art. 8) · reproduction (Art. 9) · public performance and communication (Art. 11) · broadcasting (Art. 11bis) · recitation (Art. 11ter) · adaptation and arrangement (Art. 12)

Moral rights (Art. 6bis): paternity and integrity

Duration (Art. 7): life of the author + 50 years as the general rule; many states now provide life + 70. India provides life + 60.

Computer programs are explicitly included under “literary works” in jurisdictions implementing Berne — a position affirmed by the WIPO Model Provisions and by TRIPS.

The three-step test — Article 9(2)

Any limitation or exception to the reproduction right must: (1) be confined to certain special cases; (2) not conflict with normal exploitation of the work; and (3) not unreasonably prejudice the legitimate interests of the author.

Transposed into TRIPS and the WIPO Copyright Treaty, this test now governs fair dealing and fair use analysis worldwide.

CSEG3060 · Unit V · Lecture 3 — The International IP System5

Framework · 3 of 3

TRIPS 1994 — minimum standards across all of IP

Negotiated during the Uruguay Round of GATT and in force from 1 January 1995 as part of the Marrakesh Agreement. TRIPS is a trade agreement, not an IP-office cooperation treaty — and that is what changed everything.

Minimum standards across eight domains

The patent obligations that bind India

Art. 27(1) — patents must be available in all fields of technology, product or process, if new, inventive and industrially applicable; and without discrimination as to place of invention, field of technology, or whether the product is imported or locally produced.

Art. 33 — the term shall not end before 20 years from the filing date.

Art. 31 — compulsory licensing is permitted under specific conditions: public non-commercial use, anti-competitive practices, or dependent patents.

Plus national treatment and most-favoured-nation treatment: any advantage granted to one member’s nationals extends to all.

Framework · 3 of 3, continued

What made TRIPS different: it can be enforced

Enforcement — Part III

Members must provide civil and administrative remedies, provisional measures including border enforcement, and criminal procedures for wilful trademark counterfeiting and commercial-scale copyright piracy.

Crucially, IP disputes enter the WTO dispute settlement system, with binding panel and Appellate Body rulings.

Two disputes worth knowing

India — Patent Protection for Pharmaceutical and Agricultural Chemical Products (DS50, 1997). Challenged India’s lack of product patent protection for pharmaceuticals, and led directly to the amendments that culminated in 2005.

United States — Section 110(5) of the US Copyright Act (DS160, 2000). Concerned exemptions for music performance in restaurants and bars.

The Doha Declaration on TRIPS and Public Health, 2001

Recognising public health concerns in developing countries, Doha clarified that TRIPS should not prevent members from taking measures to protect public health. It affirmed the right to use compulsory licensing and parallel importation of patented pharmaceuticals, and a 2003 waiver permitted export of products manufactured under compulsory licence.

The operative language: TRIPS “should be interpreted and implemented in a manner supportive of WTO members’ right to protect public health and, in particular, to promote access to medicines for all.”

Doha is the reference point for every argument about TRIPS flexibilities — the theme that returns on slide 12.

Institutions

WIPO — five functions, and why they matter to you

1 · Treaty administration

Paris, Berne, the PCT, the Madrid System for marks, the Hague System for designs, Lisbon, Budapest.

2 · International registration systems

The operational machinery behind PCT, Madrid and Hague filings.

3 · Policy coordination

Intergovernmental negotiation on emerging issues — genetic resources, traditional knowledge, and AI.

4 · Technical assistance

Capacity building for developing countries: training, legislative advice, and databases such as PATENTSCOPE.

5 · Dispute resolution

Arbitration and mediation, including domain-name disputes through the WIPO Arbitration and Mediation Center.

Also

WIPO administers the International Patent Classification (IPC) and the Nice Classification for trademarks — the vocabulary your classification search in Lecture 2 depends on.

WIPO and the WTO cooperate under a 1995 agreement to provide technical and legal assistance on TRIPS implementation. Division of labour: WIPO runs the procedures, the WTO enforces the obligations.

The landscape · 1 of 2

Where the world is filing

Volume

Global patent applications have grown from roughly 1 million in the early 2000s to over 3.5 million in recent years.

Driven by rising R&D investment, strategic patenting by corporations, the spread of patent systems into emerging economies, and growth in software, biotech, AI and clean energy.

Geographic concentration

Activity remains highly concentrated. CNIPA (China), USPTO, JPO, KIPO and the EPO account for the overwhelming majority of filings.

China overtook the United States as the largest filing office around 2011–12, and the gap has widened substantially since. Five of the top ten offices are now in Asia.

Sectoral distribution

  1. Digital communication and computer technology, including AI and ML
  2. Electrical machinery and energy — batteries, semiconductors, renewables
  3. Pharmaceuticals and biotechnology
  4. Transportation — EVs, autonomous driving
  5. Medical technology

Developing countries

India has emerged as a significant pharmaceutical and IT filer, while remaining historically cautious about expansive patentability · Brazil has strengthened its system while retaining health flexibilities · African IP is moving toward a regional framework under the AfCFTA protocol · China has moved from being primarily a receiving country to a major source of PCT filings.

The landscape · 2 of 2

Four live controversies in computer science patenting

Software patent eligibility

Remains genuinely contested, with the USPTO and EPO applying different tests. Indian law excludes computer programs per se under Section 3(k) but admits software-implemented inventions with a technical effect.

The consequence: the same invention may be patentable in one jurisdiction and ineligible in another. Filing strategy has to account for this.

AI-generated inventions

Several jurisdictions have had to decide whether an AI can be named as inventor. The Thaler v. Comptroller General line of cases — in the UK, at the EPO and elsewhere — has consistently held that an inventor must be a natural person.

Open source and patents

Tension between open-source licensing and patent aggression has produced defensive institutions: the Open Invention Network, the LOT Network, and patent non-assertion pledges.

Standard-essential patents

Patents covering technologies written into standards — 4G/5G, Wi-Fi, video codecs — raise complex FRAND licensing questions: fair, reasonable and non-discriminatory terms, and what those words mean when billions are at stake.

All four controversies share one root: software is cheap to copy, global on release, and hard to characterise as either a machine or a text. Every jurisdiction has answered that question slightly differently, and the divergence is the subject of the next slide.
CSEG3060 · Unit V · Lecture 3 — The International IP System11

The debate

Harmonisation — a spectrum, five drivers, six obstacles

Minimum standards

Setting baseline obligations — the TRIPS approach.

Substantive

Aligning the actual content: definitions of patentability, term, scope.

Procedural

Aligning administration and examination standards.

Unification

A single supranational right — the European Patent with Unitary Effect.

Five drivers

Trade integration — divergent laws create compliance cost · technology convergence — digital technologies make territorial distinctions anachronistic · patent quality — inconsistent standards invite forum shopping · administrative efficiency · anti-counterfeiting across global supply chains

Initiatives: the IPC under the Strasbourg Agreement (1971) · the Patent Law Treaty (2000), harmonising formal requirements · the Substantive Patent Law Treaty negotiations (2000–06), which stalled over disclosure requirements and prior user rights · the EPC and Unitary Patent · ARIPO, OAPI, EAPO, the GCC Patent Office

Six obstacles

National sovereignty — especially on public health, traditional knowledge and development · diverse legal traditions — common law versus civil law · development levels — resistance to standards seen as locking in advantages for advanced economies · political economy — industry lobbying · emerging issues — AI and blockchain outpace diplomacy · enforcement variability even where laws align

The standing tension: TRIPS-plus obligations in bilateral and regional FTAs (longer terms, data exclusivity, stricter enforcement) against TRIPS flexibilities (compulsory licensing, parallel importation, transition periods) that developing countries seek to preserve. Doha 2001 came down on the side of the flexibilities.
CSEG3060 · Unit V · Lecture 3 — The International IP System12

Strategy

Six questions before you file in a second country

1 · Commercial markets

Where will the invention be manufactured, sold or licensed? File where the money is, not where the lab is.

2 · Competitor activity

Where do competitors file, and where is infringement most likely to occur?

3 · Enforcement infrastructure

Which jurisdictions actually offer effective patent enforcement? A right you cannot enforce is an expense.

4 · Cost–benefit

Filing costs across jurisdictions weighed against anticipated returns. A five-country national phase runs USD 15,000–80,000 with attorney fees and translations.

5 · Publication strategy

Premature publication prejudices patentability, and grace periods are limited and jurisdiction-specific.

6 · Open-source considerations

Disclosure through GitHub, arXiv or a conference paper affects novelty. Timing relative to filing is a decision, not an accident.

The rule this generates

Publishing a paper on arXiv before filing in a strict-novelty jurisdiction destroys novelty. Researchers must either time publications around filings, or file before disclosure. There is no third option.

CSEG3060 · Unit V · Lecture 3 — The International IP System13

Two routes

Paris Convention direct filing versus the PCT route

DimensionParis Convention direct filingPCT route
Initial costLower — no PCT feesHigher — PCT fees payable up front
Delay before national filingsNone — must file within 12 monthsApproximately 18 additional months
Procedural consolidationNoneUnified international phase
Search report availableNo, unless requested individuallyYes — the ISR from the ISA
Suitable forSingle-country filings or rapid prosecutionMulti-jurisdiction filings with a delayed decision
Jurisdictions typically pursued1–23 or more

The decision rule

If you know now which one or two countries you want and you are ready to prosecute, the Paris route is cheaper and faster.

If you want three or more jurisdictions, or you need time and information before committing, the PCT buys you both — at a price.

What the PCT is not

The PCT does not grant an international patent. It is a filing and search procedure. National phase entry remains complex and jurisdiction-specific, and fees accumulate across both phases. Every patent you end up with is still a national patent.

CSEG3060 · Unit V · Lecture 3 — The International IP System14

The PCT · 1 of 4

Five bodies, and what each one does

IB

International Bureau, within WIPO in Geneva. Administers the treaty, publishes applications, and transmits documents.

RO

Receiving Office — the national or regional office, or WIPO itself, where the application is filed.

ISA

International Searching Authority — conducts the prior-art search and issues the ISR and Written Opinion.

IPEA

International Preliminary Examining Authority — performs the optional, non-binding preliminary examination under Chapter II.

DO / EO

Designated / Elected Offices — the national or regional offices that actually examine and grant in the national phase.

Structural highlights

Concluded in 1970, in force from 1978, with over 150 contracting states. India joined on 7 December 1998, designated the Indian Patent Office as a Receiving Office, and later acquired ISA and IPEA status — so an Indian applicant can now have the search done domestically.

Five objectives of the PCT

Unified filing — one application with the effect of a national filing in every designated state · avoiding duplication of search and examination effort · extended priority period, deferring national costs · information dissemination through publication of applications and search reports · facilitating technology transfer, particularly for developing countries.

CSEG3060 · Unit V · Lecture 3 — The International IP System15

The PCT · 2 of 4

The international phase, step by step

01

Filing. A single application at a competent Receiving Office — Form PCT/RO/101 or ePCT — comprising a request, description, one or more claims, drawings if applicable, and an abstract. Pay transmittal, search and international filing fees. The filing date becomes the international filing date if PCT Article 11 minimums are met.

02

International search, ~16 months from priority. The ISA issues the International Search Report — relevant prior art with classification codes — and a Written Opinion, a preliminary, non-binding view on novelty, inventive step and industrial applicability. The applicant may amend claims before publication.

03

International publication, ~18 months from priority. The International Bureau publishes the application as filed, any amended claims, and the ISR, via PATENTSCOPE. Publication confers provisional protection in designated states.

04

Supplementary international search (optional). A second ISA covers prior art the main search may have missed — non-English documents, specialised databases.

05

International preliminary examination (optional, Chapter II). Demand filed on Form PCT/IPEA/401 within 22 months of priority. The IPEA issues the IPRP — non-binding, but persuasive, and it lets you amend to address substantive objections before incurring national costs.

CSEG3060 · Unit V · Lecture 3 — The International IP System16

The PCT · 3 of 4

The national phase — where it becomes real, and expensive

Five obligations at entry

  1. Deadline — generally 30 months from the priority date; some offices allow 31 or 32, including Australia and Europe
  2. Translations into the official language of each designated state
  3. National fees — filing, examination, grant and annuities
  4. Local representation — patent attorneys in most jurisdictions
  5. National examination under each state’s own substantive law

What carries over

The international search and examination may be used by national offices. Several, including the EPO and JPO, offer accelerated examination on the strength of PCT results, and the Patent Prosecution Highway formalises this.

What does not carry over: the grant decision. Each office applies its own patentability law — which is why a claim that survives at the EPO may fail under §101 in the United States or Section 3(k) in India.

Regional routes

Applicants may file a direct regional application (for example a European application at the EPO), enter the PCT regional phase (the route most PCT applicants use for European validation), or validate through a regional office such as ARIPO designating multiple African states.

Regional systems worth knowing

EPC / EPO — a single grant validated nationally, plus the Unitary Patent · ARIPO and OAPI — anglophone and francophone Africa · EAPC — Eurasian states · GCC Patent Office

PCT international application filedup to 12 months
ISR and Written Opinion~16 months
International publication~18 months
Deadline for Chapter II demand22 months
National phase entry30 months (31 in some)
Restoration opportunityafter 30 months, conditional

PCT Rules 26bis.1 and 26bis.3 allow restoration of the right of priority in designated offices; many offices permit late national phase entry on additional fees.

Fees

International phase: transmittal fee (varies by RO) · international filing fee ~CHF 1,330 for the first 30 sheets · search fee, CHF 200–2,000 depending on the ISA · preliminary examination fee under Chapter II · supplementary search fee if requested.

National phase: varies greatly — filing, examination, grant and annuities. A typical five-country filing runs USD 15,000–80,000 including attorney fees and translations.

Reductions that apply to you: 75% off international filing, search and preliminary examination fees for natural persons and small entities from eligible developing countries · 90% for academic institutions in certain states · ePCT online filing discounts.

CSEG3060 · Unit V · Lecture 3 — The International IP System19

Comparative law · 2 of 2

Four tests for the same question: is software patentable?

United States — the Alice/Mayo two-step

Step 1: does the claim recite a patent-ineligible concept — a law of nature, natural phenomenon, or abstract idea?
Step 2: if so, is there an inventive concept sufficient to transform the claim into a patent-eligible application?

Many software and AI claims have been invalidated under this framework, especially pure business methods and abstract algorithms. Claims tied to specific technological improvements or novel hardware architectures are far more likely to survive.

Europe — technical character (COMVIK, T 641/00)

A computer-implemented invention is examined for technical character: it must produce a technical effect beyond the normal interaction between software and hardware.

The 2024 EPO Guidelines clarify that AI and machine learning are acceptable as technical means when applied to a technical purpose; mathematical methods alone are not patentable but may contribute to technical character; and training methods for neural networks may be patentable where the trained network has a technical application.

China

Now a leading jurisdiction for AI-related filings. Examination guidelines recognise AI, big data and blockchain as technical fields where a concrete technical solution is disclosed.

India — Section 3(k)

Computer programs per se and algorithms are excluded. Software-implemented inventions demonstrating a technical effect or technical advancement remain patentable under the revised guidelines. This is the narrowest of the four in practice.

The drafting lesson is identical in all four: claim the technical improvement, not the idea. A claim framed as “a method of training a neural network wherein the gradient update uses a novel pruning threshold” survives where “a computerised method of doing X” does not.
CSEG3060 · Unit V · Lecture 3 — The International IP System20

Putting it together

A federated learning algorithm, five countries

Scenario — a university research team in India develops a novel federated learning algorithm with privacy-preserving enhancements, and wants protection in the US, Europe, China, Japan and South Korea.

Without the PCT — the Paris route

File a provisional in India to establish the priority date. Then, within 12 months, file five separate national applications — five sets of translations, five sets of attorney fees, five prosecutions, all committed before any search result is available.

The decision to spend in all five countries must be made at month 12, on no information beyond your own searching.

With the PCT

Month 0 — Indian provisional establishes priority

Month 12 — one PCT application at the Indian Patent Office as RO

Month 16 — ISR and Written Opinion arrive; first real evidence on patentability

Month 18 — publication on PATENTSCOPE; may attract licensees

Month 22 — optional Chapter II demand to refine claims

Month 30 — enter national phase only in the countries still worth it

Eighteen additional months of information and market evidence, and the option to abandon before spending if the ISR is unfavourable.

The jurisdiction-specific work that remains

Even with the PCT, the claims will likely need different emphasis in each national phase: framed around technical character for the EPO, around a specific technological improvement for the USPTO under Alice, and around technical effect for India under Section 3(k). The PCT buys time and information — it does not buy uniformity.

What you must be able to do

Seven takeaways

  • Paris 1883 — national treatment and the 12-month right of priority
  • Berne 1886 — automatic protection without formalities, plus moral rights and the three-step test
  • TRIPS 1994 — minimum standards across all IP, with binding WTO dispute settlement. That is the difference
  • WIPO runs the procedures; the WTO enforces the obligations
  • Filing is concentrated in five offices, led by China since 2011–12, and dominated by digital and computer technology
  • The PCT is a filing and search procedure, buying 18 extra months and an ISR — not an international patent
  • Software patentability diverges sharply: Alice in the US, technical character at the EPO, Section 3(k) in India

Exam focus

  1. The core principle of Paris, Berne and TRIPS, and the comparison table
  2. The right of priority: 12 months for patents, 6 for designs and marks
  3. TRIPS Article 27(1), 31 and 33 — subject matter, compulsory licensing, term
  4. The Doha Declaration and TRIPS flexibilities versus TRIPS-plus
  5. Paris route versus PCT route — when each is correct
  6. PCT milestones: 12, 16, 18, 22, 30 months, and what happens at each
  7. The five PCT bodies: IB, RO, ISA, IPEA, DO/EO
