Eureka Patent Portfolio Analysis

One pulse in February, then everything

The $20M Series B was announced on 1 February 2020. That is the single visible money event in Eureka's record, and it lands almost exactly halfway through a filing history that starts in March 2005 and runs to a published filing dated September 2025. Twenty years of activity, one funding pulse. The interesting thing about the date is what sits directly on top of it.

Eureka is an Indonesian company tagged as Analytics. The money arrived in 2020, and 2020 is also the heaviest filing year in the entire record. That correlation is the obvious reading, and it is the one most readers would stop at. The file rewards going further, because the volume in 2020 was not the beginning of anything. The beginning was fifteen years earlier, and it was very quiet.

Ninety-one closed, nine still open

Of the hundred families, 91 are granted and 9 remain published and pending. A 91 percent grant rate is unusual at any scale, and at a hundred families it is not a rounding artefact. Something in how these applications were drafted, or in what they claimed, got them through. The nine still open are the newest end of the file, which is what you would expect from a record whose most recent published filing is dated September 2025.

A lopsided split like this tells you two things at once. First, the office outcomes are settled: there is very little left to argue about across the bulk of the file. Second, whoever prosecuted these applications did it consistently over twenty years, in ten separate offices, without the abandonment rate that usually accompanies opportunistic filing. Consistency at that level is normally the signature of a very small drafting team.

Ninety-one of a hundred families are granted, which is not a rounding artefact.

Twelve years of trickle, then a wall

From 2005 to 2012, Eureka filed ten families in total: one in 2005, three in 2006, one each in 2007 and 2008, two in 2010, one in 2012. Then nothing recorded for four years. Then 2017 arrives with 18 families, 2018 with 11, 2019 with 9. The funding mark in February 2020 sits on top of a curve that had already turned upward three years earlier, and 2020 itself brings 33.

After the peak the rate falls back: 5 in 2021, 8 in 2022, 3 in 2023, 2 in 2024, 2 in 2025. The shaded recent window will fill in as applications publish, so the last two years are provisional. But the shape through 2022 is firm. The money did not start the filing programme. It arrived at the top of a run that was already three years old and doubled its biggest year.

Eighteen dots, and one of them matters

Eighteen inventors are named across the hundred families. HU YAJUN is named on 88 of them. The next two names in the file, KHUZIN RENAT MARATOVICH and PENTLAND PHILIP EDWARD, appear on one family each. That is the whole distribution: one person carrying almost the entire twenty-year record, and a long tail of single appearances around him.

Concentration this extreme changes what the grant rate means. The 91 percent is not an institutional drafting standard; it is one inventor's twenty-year habit, repeated. It also explains the consistency across ten offices. And there is a second trace: HU YAJUN appears 48 times among the parties citing these filings, more than any organisation in the record. The same name is on both sides of the citation ledger.

One person is named on 88 of 100 families, and the next name appears once.

Ten offices for a hundred families

The families appear in the United States, Europe, China, Japan, Korea, Great Britain, Australia, Italy, Poland and Serbia. Ten offices, PCT aside. The first five are the standard set for anyone filing seriously. The last five are not routine. Italy, Poland and Serbia in particular are deliberate choices, made one at a time, with the fees and translations that come with each.

Ten jurisdictions is an expensive footprint for a hundred families, and an extraordinary one for a file written largely by a single named inventor. The recent titles in the record are a height adjustable pet bathtub, something called Real mind matching, and two separate filings titled Desk. Those are not the subjects you would predict from a company tagged Analytics, and the geography does not follow from the tag either.

Whose record is this, exactly

Put the pieces together. A filing history beginning in March 2005. A funding round in February 2020 that arrived after the acceleration, not before it. Ninety-one grants out of a hundred. Ten offices including Italy, Poland and Serbia. Eighteen named inventors, one of whom accounts for 88 families. And the same individual name appearing 48 times among those citing the work.

This is a personal inventive record that a company has been built around, rather than a company programme that happens to have a prolific inventor. That distinction matters for anything you want to conclude about durability. Institutional filing survives the departure of any one person. A file shaped like this one is bound to a single career, and everything downstream of it inherits that dependency.
