Patents explained

Why patents matter, and how
the world's systems differ

A patent is a bargain: you tell the world exactly how your invention works, and in return you get a time-limited right to stop others from copying it. Simple in principle, but the rules change as you cross borders. Here is the shape of it, with Singapore as our worked example, next to the United States, the international PCT route, and the other big markets.

Why it matters

Innovation is only worth what you can protect

shield

A moat for your idea

A granted patent lets you stop others from making, using, or selling your invention, turning a clever idea into a defensible asset.

trending_up

An asset you can bank

Patents can be licensed, sold, or used to raise money. Investors and partners treat patent-pending status as real credibility.

public

A public good

In exchange for protection, your invention is published. The system rewards inventors and grows the shared store of knowledge.

The basics, everywhere

What every patent office is really asking

The names and forms differ, but almost every jurisdiction weighs the same three questions, then grants a right that is territorial and time-limited.

fiber_new

Is it new?

Novelty. Your invention must not already exist in the public record anywhere in the world.

lightbulb

Is it non-obvious?

Inventive step. It must not be an obvious next move for someone skilled in the field.

precision_manufacturing

Can it be made or used?

Industrial applicability. It must be capable of being made or used in practice.

Two more rules hold nearly everywhere: patents are territorial (a Singapore patent protects you in Singapore, not the United States), and almost every country is first-to-file, so the filing date, not the invention date, usually wins. Protection typically lasts up to twenty years from filing.

Prior art

The single thing that decides your patent

Prior art is everything already public, anywhere in the world, before your filing date: patents, applications, products, research papers, even a forum post. Your invention has to be new and non-obvious over all of it. Miss one key reference and a patent is weak, or later invalid.

travel_explore

A preliminary read, free

Early in Observe, a fast web-based search gives you an initial picture of what is already out there, before you spend anything structural.

database

Our patent database, 250M+ records

When you have a real draft, IPGuru runs a comprehensive search across more than 250 million patents, applications, and technical disclosures worldwide, matched against your actual claims.

insights

Scored, so you know what to do

Every result is scored for relevance and risk, and the analysis names exactly what to strengthen or narrow. Then the mock examiner tests it.

The search runs twice by design: a quick preliminary pass to validate the idea for free, and a deep pass against your drafted claims when it counts. It is a built-in IPGuru capability, included in your grade, not a separate subscription.

Same idea, different rules

How the big offices differ

The sharpest differences are in how prior art is handled and how examination is run. This is where a one-size template falls down, and where IPGuru tunes the work to the office.

SG · IPOS

Singapore

Our launch market
  • check First-to-file. IPOS examines novelty, inventive step, and industrial applicability.
  • check Request search and examination within 36 months of the filing or priority date.
  • check The Patent Prosecution Highway can bring a first office action in about six months.
  • translate Language: filed and published in English.
US · USPTO

United States

Duty of candor
  • check First-inventor-to-file since the America Invents Act took effect in 2013.
  • check A duty of candor: you must disclose all known material prior art in an Information Disclosure Statement, and keep disclosing.
  • check Failing to disclose can render a granted patent unenforceable.
  • translate Language: English; a foreign-language filing needs a translation.
EP · EPO

Europe

One filing, many states
  • check A single application is examined once, then validated in the member states you choose.
  • check A nine-month window lets third parties oppose a granted patent.
  • translate Language: English, French, or German; claims translated into the other two at grant.

Highest volume
  • check First-to-file, and the world's busiest patent office by filings.
  • check Utility-model patents offer a faster, lower-bar route alongside invention patents.

JP · JPO

Japan

Rigorous examination
  • check First-to-file; request examination within three years of filing.
  • check Known for a rigorous inventive-step assessment.

KR · KIPO

Korea

  • translate Language: Korean; an English filing is accepted with a later translation.
IN · Indian Patent Office

India

Technical effect matters
  • check First-to-file; examination on request.
  • check Software and business methods face limits; a genuine technical effect is key.
  • translate Language: filed in English or Hindi.
AU · IP Australia

Australia

Straightforward path
  • check First-to-file, with a clear examination path for standard patents.
  • check Innovation patents have been phased out; standard patents remain.
  • translate Language: filed and published in English.
GB · UK IPO

United Kingdom

Combined search and exam
  • check First-to-file, with combined search and examination options.
  • check No United-States-style duty to disclose prior art.
  • translate Language: filed and published in English.

Language matters: many offices require the application in a local language, and a filing may need translating for publication. IPGuru files in English at launch (Singapore, through IPOS). Support for other filing and publication languages is on the roadmap.

Filing internationally

The PCT route: one start, many countries

The Patent Cooperation Treaty lets you file a single international application that preserves your priority date across its 158 contracting states. It buys you time, up to about thirty months from your first filing, to decide which countries are actually worth pursuing before you pay for each one.

The PCT is not a global patent. There is no such thing. It is one starting point and a clock. When the clock runs down, you enter the national phase in each country that matters, and each office examines under its own rules, the ones above.

How inventors use it

  • looks_one File first in your home office, for example IPOS in Singapore.
  • looks_two Within twelve months, file one PCT application to hold your date everywhere.
  • looks_3 By about thirty months, enter the national phase only where you want protection.

Where IPGuru fits

We tune the work to the office

Because the rules differ, the draft and the pack should too. Our jurisdiction rules engine writes to each office's conventions, so you are not filing a generic document.

rule

Jurisdiction rules engine

The draft is written to the target office's conventions, and the filing pack is formatted to its requirements, forms, and fees.

fact_check

Prior-art disclosure, handled

Where an office requires it, notably the United States IDS, the disclosure is compiled automatically from your project's prior art for you to approve.

folder_special

Ready for your attorney

The plain-English reading and the attorney binder make the handoff to a local patent attorney fast, wherever you file.

At launch, IPGuru supports Singapore national filing through IPOS, via invent.sg. More jurisdictions and the international PCT route are on the roadmap. This page is a plain-language overview, not legal advice; for your filing, work with a qualified patent attorney.
