Titanium Complex Grease: An Older Indian Patent Worth Revisiting
IOCL’s US 7,767,634 (2010) combined a titanium complex grease with mineral/synthetic oil and a conventional soap (LiX, CaSX or AlX). Drop point, EP, antiwear, oil separation and shelf life were the claimed gains. It did not become the…
Direct answer
IOCL’s US 7,767,634 (2010) combined a titanium complex grease with mineral/synthetic oil and a conventional soap (LiX, CaSX or AlX). Drop point, EP, antiwear, oil separation and shelf life were the claimed gains. It did not become the world’s default — which is exactly why an independent formulator should explain when titanium chemistry is still worth a trial.

- US 7,767,634 (IOCL, 2010) is older Indian titanium-complex grease art. It is prior art for a lithium-alternative complex soap, not a current commodity SKU. Drop point and water claims still need your oils and your mill.
- Name the test method on any number that reaches a TDS.

Lubechem will not invent a client list or a certificate. If the next step is a trial, send the duty brief. If the next step is legal clearance of a filing, that sits with a patent attorney.

How to use this filing as prior art — not as a recipe
| Question | What to extract | What not to do |
|---|---|---|
| What problem is claimed? | Titanium Complex Grease: An Older Indian Patent Worth Revisiting | Do not treat the abstract as a proven plant SOP |
| Thickener / additive families named | titanium complex grease | Do not copy claim language into a TDS |
| Examples vs claims | Worked oils, solids, treat ranges in examples | Examples are not a licence |
| Design-around | Unclaimed process windows, other thickeners | FTO is legal advice; Lubechem does not issue it |
| Citation in this article | US 7,767,634, Indian Oil Corporation, 3 Aug 2010 | Cite, do not reproduce claims |
People-first note: this is dated editorial for decision-making. It is not a scaled rewrite of the manufacturing pages, and it is not legal or certification advice.
Questions plants actually ask
Is titanium complex grease a drop-in for whatever we run today?
Almost never. Thickener family, base-oil viscosity, NLGI grade and additive response all have to be matched to the duty. A purge plan comes before a plant-wide switch. Compatibility charts are screens, not guarantees.
Can we put titanium complex grease on the TDS because a patent or paper mentioned it?
No. Patents are prior art. Papers are evidence under stated conditions. A TDS line has to be backed by a method you actually ran, on oil you actually stock, at a treat you can buy twice.
Who owns the formula if Lubechem develops it?
Ownership is the contract. The practice is independent formulation with IP transfer as scoped — not a branded additive package you can never leave. Ask for the assignment language before the first kettle.
What should Specialty grease plants looking beyond CaSX send in the first brief?
Duty (load, speed, water, temperature, relube), the current TDS and fail mode, target specs (IS / ASTM / OEM), and whether the product is sold, used in-house, or exported. Photographs of the failed component help more than adjectives.
