The most complete Singapore patents scraper available. It returns every field the Singapore (SG) patent record exposes, including publication and application numbers, applicant and assignee (the owning company), the full inventor list, priority, filing and publication dates, legal status and CPC/IPC technology classifications, plus derived counts, and gives you five filters to target exactly the patents you need.

What it does

The actor searches Singapore (SG) patent publications for each keyword and filter you pass, collects the matching patents newest first, and writes one normalized record per patent to the run's dataset. With full details enabled, each patent is enriched from its detail page with the application number, the complete applicant and inventor lists, CPC/IPC technology classifications, a PDF link and a longer abstract. Duplicate publications are removed across keywords and pages, missing source values are returned as null, and derived counts (applicantsCount, inventorsCount, classificationsCount) plus a topClassification are computed for faster analysis.

Quickstart

Open the actor, paste this into the input, and press Run. It returns up to 10 recent Singapore semiconductor patents with full details.

{
  "keywords": ["semiconductor"],
  "includeDetails": true,
  "maxPatents": 10
}

Every input field is optional. Leave keywords empty to return the newest Singapore patents with no keyword filter.

Input reference

Field	Type	Required	Default	Description
keywords	string[]	no	(empty)	One or more keywords or phrases matched against title, abstract and full text. Each keyword runs as a separate search. Empty returns the newest Singapore patents.
assignee	string	no	(empty)	Only return patents owned by or applied for by this company or organization, for example DSO National Laboratories, Grab, Sea Limited.
inventor	string	no	(empty)	Only return patents naming this inventor.
status	enum	no	ANY	Grant status. One of ANY, GRANT (granted patents only), APPLICATION (pending applications only).
filedAfter	string	no	(empty)	Only patents with a priority date on or after this date (YYYY-MM-DD).
filedBefore	string	no	(empty)	Only patents with a priority date on or before this date (YYYY-MM-DD).
includeDetails	boolean	no	true	When on, each patent is enriched with its application number, full inventor and applicant lists, CPC/IPC classifications, PDF link and a longer abstract. Turn off for a faster, lighter run.
maxPatents	integer	no	10	Maximum number of patents to collect across all keywords.

Filters combine with logical AND. includeDetails enrichment is billed additively per enriched record (see Billing).

Output reference

Run via API and CLI

Start a run and wait for it to finish, then read the dataset. Replace <TOKEN> with your Apify API token.

Run synchronously and get dataset items in one call:

curl -X POST "https://api.apify.com/v2/acts/scrapers_lat~singapore-patents-scraper/run-sync-get-dataset-items?token=<TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"keywords":["semiconductor"],"status":"GRANT","includeDetails":true,"maxPatents":25}'

Start a run asynchronously:

curl -X POST "https://api.apify.com/v2/acts/scrapers_lat~singapore-patents-scraper/runs?token=<TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"assignee":"Grab","maxPatents":100}'

Apify CLI:

apify call scrapers_lat/singapore-patents-scraper \
  --input '{"keywords":["battery"],"filedAfter":"2021-01-01","maxPatents":50}'

Fetch results

Every run writes to a dataset. Fetch items as JSON, CSV, or Excel by changing format:

# JSON
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&clean=true&format=json"

# CSV
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&clean=true&format=csv"

# Paginate large datasets
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&offset=1000&limit=1000"

<DATASET_ID> is returned as defaultDatasetId in the run object. Use offset and limit to page through large result sets. clean=true drops empty and internal fields.

Billing and limits

• Pay per result. You are charged per patent returned (result event). See the pricing tab for the current per-result price.
• Full-details add-on. When includeDetails is on, each patent that gains real detail-page enrichment charges a small additional details event. Turn includeDetails off to avoid it.
• No charge on failure. If no patents match or the source is unreachable, the actor writes a single non-billable diagnostic item with a populated error field. Empty runs cost nothing.
• Spend cap respected. Set maxTotalChargeUsd on the run; once reached, the actor stops emitting and charging further billable results.
• Free Apify plans are capped at 10 records per run. Upgrade for higher maxPatents.

FAQ and troubleshooting

A run returned no patents. Why? The keyword and filters matched nothing. Try a broader keyword, remove the date range, or check the applicant/inventor spelling. Zero-result runs are not charged.

What does the applicant/assignee field represent? The corporate owner of the patent. Use assignee in the input to pull every Singapore patent owned by one company.

How do I get only granted patents? Set status to GRANT. Use APPLICATION for pending applications only.

Why is legalStatus null? Singapore stage data was not available or was reported as unknown for that family. Missing source values are returned as null, never invented.

What do the classification codes mean? They are CPC/IPC technology classifications. topClassification is the primary code and classificationsCount is the total, useful for grouping patents by technology area.

Is this an official patent office tool? No. This actor is independent and has no affiliation with IPOS, Google, or any patent office. It reads only publicly available patent data. Use the results in accordance with the source's terms.
