Use the two financial-year series to compare the same application route.
Tamil Nadu and Karnataka added the most among these rows
Tamil Nadu's increase from 9,507 to 15,347 is about 61%. Karnataka rose from 6,025 to 8,319, about 38%, and passed Maharashtra on this measure. These shifts compare filings attributed to the same jurisdiction over two consecutive financial years. Source 1
A small base changes the growth comparison
Odisha rose from 350 to 1,656 applications, adding 1,306. That is a much higher percentage increase than Tamil Nadu's, even though its absolute increase is far smaller. Punjab's 143 decline and Gujarat's increase of 30 show how widely trajectories diverged. Source 1
The patent office separates filing routes
The table puts ordinary, convention and national-phase applications in separate columns. The chart uses the ordinary column for both years. Adding the other routes would answer a broader question and change the figures for states with filings through those channels. Source 1
Applications count requests for protection
The numbers refer to applications recorded in the fiscal year. The patent office reports grants and other processing stages separately. A filing count can reflect greater use of the patent system, but it cannot establish what share of these applications will be granted or commercialised. Source 1
