Sahalovy.ch Patent Landscape
About the data: built from public internet sources such as company websites, patent databases, publications and conference materials.
Public view: this page shows only a small part of the working registry; detailed notes and source trails stay private.
Current patent view
The detailed patent work stays in the internal registry: family grouping, assignee links, inventor connections, source notes and review history.
The numbers can change as families are merged, corrected or expanded.
Patent-family structure
These views are generated from the physical Patent_Family_Index. Classification counts overlap because one family can carry several CPC/IPC branches. Priority-year bins are mutually exclusive; 115 families currently have no single year that can be read safely from the stored priority field.
Only aggregate counts are published. Family-level genealogy, source trails, internal review notes and detailed relationships stay private.
Coverage in the physical family index
Technology branches
| Classification branch | Families |
|---|---|
| H01J37 / H05H | 275 |
| C23C14 | 230 |
| C23C16 | 121 |
| F03H | 113 |
| C23C8 | 100 |
| F04B / F04C / F04D | 69 |
Classification counts overlap: one family can belong to more than one branch.
Priority-year distribution
| Period | Families |
|---|---|
| ≤2009 | 247 |
| 2010–2014 | 114 |
| 2015–2019 | 196 |
| 2020–2024 | 503 |
| 2025–2026 | 76 |
| Unresolved / non-standard priority field | 115 |
Priority-year bins are mutually exclusive and total 1,251 families.
How the main patent branches are distributed over time
Counts use readable priority years from the physical Patent_Family_Index. Technology rows overlap because one family can carry several CPC/IPC branches, so the rows must not be summed into the canonical family total.
| Branch | ≤2009 | 2010–2014 | 2015–2019 | 2020–2024 | 2025–2026 |
|---|---|---|---|---|---|
| H01J37 / H05H | 49 | 21 | 40 | 140 | 19 |
| C23C14 | 55 | 30 | 38 | 74 | 27 |
| C23C16 | 12 | 4 | 15 | 74 | 13 |
| F03H | 33 | 11 | 23 | 34 | 7 |
| C23C8 | 38 | 15 | 13 | 15 | 12 |
| F04B / F04C / F04D | 22 | 6 | 8 | 31 | 2 |
