An empirical index of 102 Indian Patent Office rows — power electronics, solar systems, mechanical plant tools, and later energy-storage filings — sourced from solarmanofindia.com/patents. This page is a research docket, not a claim that every row is a grant.
1. The R&D path: invent and file, don’t assemble a copy
The market Su-Kam entered was an unorganised Indian power-backup trade: local assemblers, metal boxes, square-wave and modified-sine output that hummed in fans. That baseline is in the founding essay, the India Today profile of 18 December 2017, and the teaching case. The opposing path on this site is first-principles hardware: MOSFET and DSP sine wave, a GE Plastics PC-ABS chassis, in-house firmware, and a plant that stacked transformer cores rather than importing a kit. Founder bios on this site also record DSIR recognition for in-house R&D. This archive does not invent a “95% of the industry copied” statistic or a 20 GHz instrument list.
How the going-concern 77 granted patents were filed is a separate essay. The table below is 102 public-docket rows (77 Su-Kam-era filings plus later Su-vastika and personal rows). Filter by technology, IPO status, or filing era. Do not treat the table as the 77-grant portfolio.
2. Six technological shifts on this docket
These cards map published essays and archive rows. A Pending application is not a grant. A grant is not a shipment census.
1. Silicon & waveforms
MOSFET switching and DSP pure sine wave to replace square-wave noise — Home UPS origin, DSP essay. Rural-grid charging down to 90V: Falcon Plus.
2. Safety & PC-ABS
Metal chassis to flame-retardant PC-ABS — Chic with GE Plastics; India Today Innovation of the Decade. Chic essay. Fairy Queen is the required commercial failure on that page.
3. Solar MPPT & PCUs
India’s first DSP-based high-voltage MPPT charge controller as published here: Indian Patent 292773 / 940/DEL/2008. MPPT essay (Solarcon on that page). Touchscreen PCU: Brainy Touch.
4. High-kVA & lift backup
Colossal 100 kVA Solar PCU and Power on Wheels: the 100 kVA essay. Elevator backup on this docket is 1432/DEL/2009 — Pending, not a grant, and not an ERD kVA table.
5. Batteries, equalizers, later lithium
Su-Kam-era equalizer filings remain Pending (e.g. 97/DEL/2009). Lead-acid BMS is in the BMS essay; LiFePO4 / Su-vastika BESS is a later era — use the era filter, do not back-date a lithium catalogue into 1988–2019.
6. Factory ATS & core stacking
Electroscopy on the dealer counter: the testing essay. Granted: electro-pneumatic core stacking, Indian Patent 291664 / 2048/DEL/2008. ATS application 1707/DEL/2008 is Pending.
3. Policy lesson: IP as a living programme, not a CIRP PDF
Patents did not vanish from a registry the morning CIRP began; the programme and the people did. The source docket also notes Su-Kam grants later ceased when renewal fees were not paid after 2019 — later lapse, not a CIRP-day deletion. That distinction is the industrial-policy exhibit: insolvency calendars do not maintain firmware teams, DSIR labs, or annuity clocks. The memorandum is Insolvency and Industrial Asset Preservation (Delhi High Court W.P.(C) 10599/2021). Teaching companion: Su-Kam Case Study 1988–2019. Kunwer Sachdev exited Su-Kam in 2019 and is not current management.
How to read the directory. Search title and numbers. Filter by technology domain, IPO status, or filing era (Su-Kam 1988–2019 / Su-vastika / personal). Each “View” link is one row’s case file. This is not a jobs census and not a claim that all 77 Su-Kam rows were grants.
