| National patent applications: – Sufficient time for writing these without needing rush-work. | 2027-04-24 (approximately) |
| Deadline (national patent applications) | 2027-07-24 (approximately) |
| One of the following two will have happened: (1) National patent applications filed. (2) The patent application has expired. | 2027-07-25 (approximately) |
Comparison of scenarios (hypothetization):
| WIKIPEDIA (cross-licensing): https://en.wikipedia.org/wiki/Cross-licensing | No further patent applications on porous turbines are filed by anyone | New patent applications become filed by others |
| Patent expires (2027-07-25) | (1) No patent license sales (revenues) (2) No cross-licensing necessary | (1) No patent license sales (revenues) (2) No cross-licensing possible |
| National patents become granted | (1) Patent license sales (revenues) (2) No cross-licensing necessary | (1) Patent license sales (revenues) (2) Cross-licensing possible |
Patent licenses:
| Patent licenses: (1) Patents are valid during 20 years. (2) Do you believe porous turbines will add customer value during these 20 years? (3) If “yes”, then part of this value could generate patent license revenues. (4) If “yes”, then these patent license revenues would motivate investments. Deadline for filing national patent applications: – 2027-04-24 (this date avoids rush work) – 2027-07-24 (formal deadline) |
The patent application &
previous technolgy:
| Previous technology (GB408690A, steam turbine): – Steam flows one single loop around a rotor. https://worldwide.espacenet.com/patent/search/family/010282533/publication/GB408690A?q=pn%3DGB408690A |
| New technology (WO2025262339, steam turbine): – Steam flows two, or more loops around a rotor. https://worldwide.espacenet.com/patent/search/family/094382820/publication/WO2025262339A1?q=pn%3DWO2025262339A1 |
Why does the number of loops matter?
| (1) More loops mean … (2) a longer steam expansion distance … … through the porous metal. This means the following can be handled… (3) … higher pressure drops (ΔP). (4) … higher temperature drops (ΔT). This means this turbine type (porous turbine)… (5) … can compete with existing turbine types. This means this turbine type (porous turbine) in some cases will be… (6) … less good than existing turbine types. (7) … better than existing turbine types. Questions for the next step: – In which products will porous turbines perform better? – Will customers soon demand these products? – Which manufacturer will fill this demand? @ Manufacturers: Which manufacturer will be the fastest at identifying the products, where this new technology performs better (and adds more customer value)? – You? – Your competitors? |
Value added
(generalized description):
| VALUE ADDED TO CUSTOMER: (1) Improved fuel efficiency of: … ICEs (internal combustion engines), … gas turbines. (2) BEV:s: Autonomy away from charging points. Examples of end-products for porous turbines (suggestions), please see: https://porousturbines.com/applications/ |
