Overview
What this dataset covers
This dataset gathers records matching a search for electronic cigarette or vaporizer devices combined with PID or proportional integral derivative control terms and temperature control. The search string sets no date limit, so the result reflects every matching record the database holds at retrieval, not a fixed year window. It spans 12 simple patent families and 29 published records, with filings at offices including the United States, China, Israel and the EPO.
With only 12 families in scope, this is a small pool. The numbers below describe what this specific search returned, not the shape of a field or an industry, treat this page as a starting point for a closer search rather than a finished map.
Families in scope, by filer and IPC subclass
Ordered by volume only, not by importance or claim strength. Counted in simple (DOCDB) patent families, so one invention filed in several countries counts once. Names come from Patsnap's standardised assignee field as recorded on each document; subsidiaries and group companies are not merged. The icon before each name is read from the name itself (words such as University, Institute or Ltd); the data carries no organisation-type field, so treat it as a reading aid rather than a classification. Filings held by named individuals rather than organisations are removed where they can be identified; that identification is not exhaustive, so an individually held filing can still appear below. Either way those filings stay inside the totals above. This table shows the top 11 of the 11 filers returned for this search; the data endpoint returns at most 100 entities, so even that 11 is not the complete set of filers. A single family can name more than one filer, so these counts overlap and do not add up to the total.

The Data
Filing activity and technology split
Two views of the same 12 families: how publications have appeared over time, and which IPC subclasses they carry.
Filing trend by earliest filing year (published records)
Published records run from 2012 (5 records) to a peak of 6 in 2019, with 2026 at 1 record so far. Records from 2022 onward are still filling in as later-filed cases publish, so the most recent years understate eventual counts, this is a publication-lag effect, not a change in filing activity.
Counted in published records by earliest filing year, not de-duplicated into families. A filing is counted in the year it was filed, but it only becomes visible after it publishes: roughly 18 months for most routes, and up to 30 months where a PCT application enters national phase. 2022 onwards are therefore still filling in and are shaded; no growth figure on this page uses them. Because this series counts documents rather than inventions, a rise can mean more inventions or the same inventions filed in more countries; this dataset cannot separate the two. This chart covers 2012-2026 (28 records); the 29 total quoted above includes earlier filings outside the window.
IPC subclass coverage (share of 12 simple patent families)
A24F (smokers' requisites) appears on 7 of the 12 families (58.3%), the highest share of any subclass here. A61B, A61M and G05B each appear on 2 of the 12 families (16.7%). A family can carry more than one subclass, so these shares add up to more than 100%.
Shares are the percentage of the 12 patent families in scope. One patent family can carry several IPC classes, so the shares add up to more than 100%.

As Filed
Method for detecting the number of puffs of an electronic cigarette, and electronic cigarette (US20210015165A1)
DONGGUAN MYSMOK ELECTRONIC TECHNOLOGY CO., LTD
The abstract describes sampling a real-time temperature of a heating unit, determining a temperature difference, integrating that difference over time to get an integral value, and calculating a limit from it. The method checks whether the real-time integral value exceeds that limit to judge whether a puff has occurred, with the limit varying as the temperature-difference pattern changes.This is the first record returned by the search under the database's default order, not the most cited, newest or broadest filing in the set. The abstract describes what it claims; it says nothing about what the granted claims actually require.
Selected as the first record the search returns under the database default order, then shown in full. It is not ranked by citations, claim breadth or commercial importance, and it is not a judgement about which filing in this space matters most.

What the numbers show
Three figures taken directly from the dataset, each counted in the unit the evidence summary attaches to it.
Largest filer
16.7%
of 12 simple patent families
Shenzhen Youme Network Tech Co Ltd
This filer is named on 2 of the 12 simple patent families in scope (16.7%), the highest single-row share among the 11 listed filers. Filer rows are not rolled up to corporate group and can overlap, so this share belongs to this one row only.
Families, not records
Filer spread
11 of 11
listed filers hold 2 or fewer families each
A long tail among listed filers
All 11 listed filers hold 2 or fewer simple patent families each. The filer list contains organisations only, filings held by named individuals are inside the totals but not in this list.

Next Steps
Where to take this from here
This page is a starting point built from one search string. The next steps depend on what decision you are trying to make.
Read the granted claims directly
A family count or an abstract cannot establish claim scope. Pull the granted claim set for any record that matters to a filing or clearance decision.
Open Eureka →Widen or narrow the search string
This dataset is built on one specific combination of terms. Related filings using different wording for temperature control or PID logic will sit outside this result and need a separate search.

FAQ
Common questions about this dataset
This search returned 12 simple patent families and 29 published records matching the combination of electronic cigarette or vaporizer terms with PID or proportional integral derivative control and temperature control. No date limit was applied, so this reflects every matching record the database holds at retrieval rather than a fixed year window. Because the search is defined by a specific string, records using different wording for the same control approach may sit outside this count.
Shenzhen Youme Network Tech Co Ltd holds the largest single-row share, named on 2 of the 12 simple patent families (16.7%). The remaining listed filers, 11 in total, each hold 2 or fewer families, and the list contains organisations only, filings held by named individuals are counted in the totals but excluded from the filer list. Filer rows are not rolled up to corporate group, so names that look related are not summed into one position.
PID, or proportional-integral-derivative, is a feedback control method that adjusts an output, here, heater power, based on the size, accumulation and rate of change of an error signal, typically the difference between a target and measured temperature. In this dataset the term appears in the search string itself, alongside temperature control, to capture records describing this kind of closed-loop heating logic. What any specific patent's claims actually require for that logic has to be read from the granted claim set, not inferred from the search terms that found it.
A24F, covering smokers' requisites, appears on 7 of the 12 simple patent families in scope (58.3%), the highest share of any subclass here. A61B, A61M and G05B each appear on 2 of the 12 families (16.7%). Because one family can carry more than one IPC subclass, these shares add up to more than 100%, and the dataset includes 11 subclasses in total, not only the four named here.
No. It reflects one search string run against one database at one point in time, returning 12 families and 29 records with no date limit. A pool this size is a starting point for further research rather than a complete map, and gaps in the result are more likely to reflect search-term limits than an absence of filings on the actual topic. Anyone relying on this for a filing or clearance decision should widen the search and read the underlying claim sets directly.

How this page was built, and what the numbers do and do not mean
Search. Every figure on this page comes from one Patsnap search, run once and not edited afterwards. This is the exact search string:
TAC:(("electronic cigarette" OR vaporizer) AND (PID OR "proportional integral derivative") AND "temperature control")Reading the field codes: TAC searches the title, abstract and claims of each record, not the full description. The search string sets no date limit, so the scope is every matching record in the database regardless of when it was filed. It is not restricted to recent years. How this string was built matters for how far the counts can be pushed. It was generated in batch from a topic list rather than hand-crafted for this page, and the result set is not manually screened. A keyword search over title, abstract and claims both over-captures (unrelated filings that happen to use the same words) and under-captures (the same invention written in different words). This page cannot measure either effect, so read every figure here as what this particular string returned, not as what exists in the field.
What is being counted. Two different units appear on this page and they are not interchangeable. The filer list and the technology split are counted in simple (DOCDB) patent families: one invention counts once however many countries it was filed in. The total, the jurisdiction split and the filing-year chart are counted in published records: the same invention counts once per publication. For this search that is 29 records and 12 families. Record counts reward filing in many jurisdictions; family counts do not. Shares are only ever taken against a denominator in the same unit, and each one names it.
Who the filers are. Names come from Patsnap's standardised assignee field, as recorded on the documents themselves. They are not rolled up to corporate group: a parent and its subsidiaries appear as separate entries, and a portfolio acquired from another company stays under the name on the document unless the assignment is reflected there. This list is meant to carry organisations, not people. Filings held by a named individual are identified by matching the assignee against the inventors on the same search, and, for names written in Chinese, Japanese or Korean characters, by the name carrying no organisational suffix; those are removed from the list. Neither test is exhaustive: the inventor list it matches against is itself capped, and a personal name written in Latin script with no organisational wording in it cannot be told apart from a short company name by rule. So an individually held filing can still appear in the list. Those filings stay inside every total and share on this page either way, so the listed entries can add up to less than the total. A record shown in full further down still names its assignee exactly as the patent office records it, including where that is a person: that name is how the record is identified and checked. What is left out of the ranking is people as ranked entries, not people as cited sources. The table shows the top 11 of the 11 filers returned, ordered by count alone; the data endpoint returns at most 100 entities, so even that 11 is not every filer. One patent family can name several filers and each is counted separately, so these rows are not slices of a divided whole: adding them together over-counts, and this page deliberately publishes no combined "top five" share for that reason. See every filer, individuals included
Dates. The year chart counts by earliest filing year, not publication year. A filing only becomes visible once it publishes: roughly 18 months for most routes, and up to 30 months where a PCT application enters national phase. Measured across these pages, the year four back from today still holds only about 89% of its eventual count. 2022 onwards are therefore shaded on the chart as still filling in. The data behind this page was retrieved on 2026-10-26.
Legal status. Legal status was not available for this search, so no in-force figure is shown. Get the status breakdown in Eureka
Classification. The technology split uses IPC subclasses (four characters, for example H01M). A single record usually carries several, so the shares add up to more than 100% and a record can appear in more than one bar. Subclass is a coarse grouping; it describes the field a record was classified into, not what the claims cover. Break the classes down to subgroup level
Who wrote the words. The tables, charts, counts, shares and patent numbers on this page are produced directly from the search result by a program; none of them are written or estimated by a language model. The surrounding prose, headings, FAQ answers and the answers in the question panel are drafted by a language model that is given those same figures and is not permitted to introduce others. Prose can still mis-describe a correct figure, so where the two disagree, the tables and charts are the record.
Disclaimer. This page is generated from Patsnap Eureka data drawn from a limited snapshot of global patent and scientific-literature records, and is provided for general information and reference only.
Patent data carries limitations that apply to every figure above. Recent filings are under-counted, because an application is not public until roughly 18 months after filing and database loading adds further delay. The search string defines and constrains everything shown: records that use different terminology, or that sit outside the fields searched, are absent and cannot be counted. Applicant names, classification codes, legal-status codes and citation records are taken as recorded and may contain errors, duplicates, omissions or stale entries. Ordering by volume is not a measure of quality, scope, enforceability or commercial value, and a larger portfolio is not a stronger one. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing on this page constitutes an exhaustive prior-art, novelty, freedom-to-operate, validity or infringement search, nor does it constitute legal, financial, investment, or professional advice, and it should not be relied upon as such. No attorney-client relationship is created by it. Any patent, commercial, or strategic decision should be verified independently against the primary records and reviewed with qualified patent, legal, and domain professionals. Patsnap makes no warranties, express or implied, as to the accuracy, completeness, or fitness for any particular purpose of the information presented.
The question panel. The answers behind the suggested questions on this page were written when the page was generated, not in response to your click. The progress steps that play before an answer appears are an animation of how that analysis was done; nothing is being searched or computed at that moment. Typing your own question instead opens Patsnap Eureka, which does run it live.
Machine translation. Assignee and organisation names originally recorded in Chinese, Japanese or Korean have been rendered into English by an AI translation step so that the tables stay readable. These renderings are best-effort and may not match a company's registered English name; the original name is what the underlying patent record carries, and it is what any Eureka query launched from this page uses.
