The direct answer
A useful provisional patent application describes the invention thoroughly enough to support the concepts you may later claim, including alternatives, drawings, and how it works. Filing a thin document can create false confidence, so founders should understand the limits and obtain professional advice when the IP matters.
Key points covered
- Document the invention, variations, and supporting drawings in detail.
- Understand that a provisional application is not an issued patent.
- Track the filing date and the deadline for any follow-on nonprovisional application.

[0:00] hey there startup people today I'm going
[0:03] to teach you how to file a provisional
[0:06] Utility Patent
[0:07] application which if you get micro
[0:10] energy status will only cost you about
[0:12] $65 so I'll step you through the process
[0:15] of writing up the specifications doing
[0:18] the
[0:18] drawings and then also how to file it
[0:22] with the patent office it's not as hard
[0:24] as it seems and you can totally do it at
[0:27] home so first things up got to say uh
[0:31] this episode is sponsored by Chuck rack
[0:34] hitch Mount ski rack just in time for
[0:36] winter right now and then if it's summer
[0:38] when you're looking at this we also make
[0:40] a bike
[0:42] rack so with that in mind let's talk
[0:47] about patents so one of the first books
[0:50] I read was called from patent to profit
[0:54] and it made me think that I could make a
[0:56] ton of money by patenting things and
[0:58] well you might be able to actually do
[1:00] that but in this book this guy's claim
[1:04] to fame Bob ma de mati medy anyways Bob
[1:11] Bob wrote about uh how he had come up
[1:14] with the little tab that's on plastic
[1:17] grocery bags that allowed you to then
[1:20] pull one side of the bag and it would
[1:21] open to put groceries in and so his
[1:24] whole book is about talking how he would
[1:27] come up with a better product and and
[1:30] then file a provisional patent and then
[1:32] as quick as he could while he still had
[1:34] provisional status try and license the
[1:37] idea and was Bob successful yes a few
[1:41] times but this is because if you read
[1:43] the book you realize Bob is a sales guy
[1:45] really yes he's an inventor but he's a
[1:48] better sales guy and able to get his
[1:50] ideas to the people who find it valuable
[1:54] who then want to pay him money for those
[1:56] ideas so if you read the rest of the
[1:59] book there's times where he had little
[2:02] products that were uh less
[2:05] successful um for example I think he had
[2:07] like a pizza slicer or something of that
[2:11] nature and he's having a hard time hard
[2:14] time trying to sell the last 2,000 units
[2:17] or whatever he had of a 10,000 or plus
[2:19] unit run and so either way even you know
[2:24] this gentleman who wrote This Book he
[2:26] had his own fair share of problems
[2:27] trying to sell merchandise that they're
[2:29] just really may not have been much of a
[2:30] solid market for but the book talks a
[2:34] great deal about the patent system and
[2:37] how to file patents and really kind of
[2:38] made it easier for me to then go about
[2:41] trying to file provisional patents and
[2:43] then maybe try and see if I could
[2:45] license them what I'm going to step you
[2:47] through right now so with that let's
[2:51] look at uh an
[2:53] example so a great example I have here
[2:58] is if I go go to drawings and I'm going
[3:01] to
[3:02] hide me so we just see
[3:05] this uh I had at one point really wanted
[3:09] to make a individual single cookie oven
[3:12] so that you could cook a cookie at your
[3:16] desk and I actually made one of these
[3:18] and it made a delicious cookie at my
[3:20] desk and it made my whole desk area
[3:21] smell like chocolate chip cookies and
[3:23] drove all my co-workers insane and it
[3:26] was pretty awesome basically the size of
[3:28] a CD ROM drive an old one even if you
[3:31] know what an old one looks like guess
[3:34] that's super dated but um kind of like
[3:37] half a pack of Oreos that's a better
[3:39] size description so either way uh it had
[3:44] a little
[3:46] arm that you could pull out a little
[3:49] tray that was like Teflon coated or
[3:51] something like that and then the outside
[3:53] was cool and then the inside was at like
[3:56] a constant temperature that would cook a
[3:58] cookie at about 300
[4:00] 10° or so and it would just sit there
[4:03] and whenever it was clicked on it would
[4:06] bake and it would self-regulate its
[4:07] temperature and whatnot so in order to
[4:11] file provisional patent first thing I
[4:13] like to do is make up drawings for
[4:16] whatever it is I'm trying to file and
[4:18] label them in this instance every single
[4:21] drawing you have you want to have a
[4:22] figure number with it so I have figure
[4:26] one and then you want to point out every
[4:29] single possible element that you in in
[4:33] your diagram and give them each unique
[4:37] numbers unless it's the same thing so
[4:39] for example here uh you know this might
[4:43] say 15 is 15 anywhere up here yes right
[4:47] there 15 so those are the same items
[4:50] that's a hinge right and so you would
[4:54] basically go through label everything
[4:56] that somebody would need to know in
[4:58] order to recreate your
[5:00] device uh and
[5:02] then basically this is good to do it
[5:05] early because then you can go and write
[5:07] your specifications which is your
[5:09] description of
[5:10] everything and you can reference these
[5:13] numbers as you do it and it'll save you
[5:14] a lot of time now something people don't
[5:17] realize is that provisional patents
[5:20] actually can have more than one idea in
[5:21] them you can have multiple ideas so
[5:24] luckily I found this old provisional I
[5:26] had filed and looked through and I had
[5:28] lots of ideas is in here because why not
[5:31] save money so here's the side view of
[5:34] the oven and then what's this this was
[5:37] actually my photo crop sharing app
[5:41] called Snicker where you would take a
[5:44] photo of something and then you would
[5:46] crop it down and then you would share
[5:50] that cropped image and then if you
[5:53] clicked on the shared cropped image it
[5:56] would then blow up and show you the full
[5:58] one that was neat here's another one I
[6:01] had which was
[6:04] a uh basically a little thermometer with
[6:07] an indicator
[6:10] light uh and it would get tossed into a
[6:14] cup of coffee and then when the coffee
[6:16] reached the perfect temperature and it
[6:18] could use for tea also coffee tea hot
[6:20] cocoa whatever but you would toss it in
[6:23] and then when it reached the preferred
[6:26] temperature to drink it would then up
[6:29] and or beep and then you would just pull
[6:33] it out and drink from your cup it also
[6:35] cooled your drink down a little bit
[6:36] quicker because it was a heat sink of
[6:39] source just because it was metal same
[6:42] reason why you put a spoon into tea is
[6:44] actually because that cools down the tea
[6:46] quicker so anyways um in this basically
[6:50] I had a uh
[6:52] diagram um of the outside and then a
[6:56] simple diagram showing the different
[6:58] components
[7:00] and then another one showing uh
[7:04] alternating
[7:06] components or an alternate version of
[7:08] the components and so all of these have
[7:11] unique numbers none of them overlap
[7:13] unless it's the same thing and these
[7:16] figures are all three different items um
[7:20] so you want to
[7:22] have your figures numbered so that you
[7:24] can reference them like I had stated and
[7:27] if you do cutaways uh having shaded
[7:30] regions is very good you don't want to
[7:32] have anything in your diagrams that
[7:35] isn't in your written
[7:38] specifications
[7:40] because then it confuses whoever is
[7:42] looking at it they'll wonder what that
[7:44] extra part is or whatnot and is it
[7:46] important is it not important especially
[7:47] if it's important you don't want to miss
[7:50] labeling it so with that in mind I wrote
[7:53] all of this and then you would go
[7:55] through and you would write your
[7:57] specifications so I put put in here the
[8:00] items and then my name and address and
[8:03] then uh here I have the first thing
[8:06] which is the single size oven and like I
[8:08] had stated in the patent search episode
[8:10] you want to put in all your relevant
[8:12] patent documents that you had found so
[8:14] these are the ones that I had found that
[8:16] were relevant at the time and then here
[8:20] is an abstract and it's very simply what
[8:23] is this uh
[8:25] then the figure list showing the
[8:29] different figures and Views so figure
[8:32] one is an isometric view of the front
[8:33] side back side uh oven with the spatula
[8:37] displaced Etc and then this is where it
[8:39] really comes in handy to have all of the
[8:41] numbers in place and by the way so those
[8:43] drawings I just took my CAD program and
[8:46] told it to do simple line drawings with
[8:49] a white background you have to have a
[8:51] white background with no
[8:54] gradient you're not even supposed to
[8:56] have color so this this image with color
[9:01] is not great now you can still submit it
[9:03] but it's not ideal ideal you have black
[9:06] and white drawings so you go back
[9:09] through here and this is where you'll
[9:11] say things like the oven as drawn in
[9:14] figure one consists of a main outer body
[9:16] 14 primarily of a low thermally
[9:19] conductive material such that it allows
[9:21] that it prevents burning of the user and
[9:24] you want to try and make this
[9:28] understandable so that anybody reading
[9:30] this will understand it and you've
[9:31] explained each one of the figures and
[9:34] numbers that you have in your drawing so
[9:37] this is nice because you can go through
[9:38] literally numerically and make sure that
[9:40] you've talked about every single one and
[9:43] the important aspects of everyone and so
[9:46] then here's the big deal at the
[9:48] end you want your claim to be as broad
[9:53] as possible and I guess I didn't bring
[9:56] up earlier on I'm not a patent attorney
[9:59] I'm not a patent lawyer and of any
[10:03] sorts do your own research in this
[10:08] and don't hold me liable for any
[10:10] mistakes you made and definitely seek
[10:12] out legal advice from a patent attorney
[10:15] prior to filing your provisional patent
[10:17] if you have any concerns about this but
[10:20] you want your claim to be extremely
[10:22] broad because the patent office their
[10:24] goal is to narrow your claims down as
[10:26] much as they possibly can which means
[10:29] that when you go to file your
[10:30] non-provisional application that is
[10:32] where you will want to narrow down to
[10:36] the specifics of what you are trying to
[10:40] patent so for
[10:44] example
[10:46] if you don't include a claim or if what
[10:51] you're trying to claim later on in your
[10:52] non-provisional application is not
[10:55] included in your claim and your
[10:56] provisional then you cannot include it
[10:58] so that's the problem with having overly
[11:02] conservative claims in your provisional
[11:04] is it limits you from having broader
[11:06] claims or other items if you change
[11:09] something a little bit in your
[11:11] provisional your non-provisional
[11:13] application so here again super broad
[11:17] what I claim is an oven which is sized
[11:19] to cook an individual baked good and
[11:22] that is all I need because it's super
[11:25] Broad and can easily be reduced finer
[11:28] and finer and finer because I'm sure by
[11:31] the time I got something written that
[11:33] the patent office would actually want to
[11:37] allow they would have narrowed it down
[11:40] to basically what would look almost
[11:43] exactly like my device and be configured
[11:46] only to cook a cookie of a specific mass
[11:49] with a specific Ratio or something to
[11:51] something which you can do in patents is
[11:53] you can specify all of that and get your
[11:56] very very narrow window
[11:59] of what is patented which is another
[12:02] reason why a lot of times patents while
[12:05] you intend them to be very valuable a
[12:07] lot of times end up extremely useless
[12:09] because they end up being very narrow in
[12:13] their claims and they're not able to
[12:16] protect anything other than exactly
[12:18] copying your specific
[12:22] design which might have been better
[12:24] protected by a design patent just C you
[12:28] know for the outside of it um but so
[12:33] then again image crop application here
[12:35] cited ones I go through abstract which
[12:39] is really just it's the abstract is the
[12:43] general as if you're conversationally
[12:45] telling somebody about it and why it's
[12:47] important it is just a summary of
[12:50] everything and then the specifications
[12:53] are the nitty-gritty of what everything
[12:55] does every
[12:57] component and again I claim is a process
[13:01] for transferring a sectionally displayed
[13:03] image to a remote
[13:04] user very simply worded and would be
[13:08] narrowed down a whole lot more and then
[13:11] same thing here for this pen I don't
[13:13] even want to get into this but so with
[13:17] that
[13:18] now you need to file this I actually
[13:21] would do all of these
[13:23] in paint in terms of adding these lines
[13:27] it's super easy and out old Ms paint um
[13:30] you can use whatever you want and then I
[13:33] copy and paste that into word and then I
[13:37] export save as PDF and then this gets me
[13:40] a nice
[13:41] PDF and sometimes you have to do like a
[13:44] print to PDF either way the patent
[13:47] office likes uh specific formats and it
[13:52] can yell at you if it is not quite the
[13:55] right PDF format which I didn't even
[13:56] know there could be slightly different
[13:58] ones until I started doing this
[14:00] so with that in
[14:02] mind um few forms that you're going to
[14:04] need you're going to need your
[14:07] application provisional cover sheet s
[14:10] sp16 and you going to have to basically
[14:12] enter in all your info here uh the name
[14:16] of the invention which is the title that
[14:18] you
[14:19] had uh um a firm or an individual name
[14:23] mailing addresses is this a
[14:27] government uh was this created under a
[14:29] government contract because if it was
[14:32] then basically the government has some
[14:34] claim to it so you'd put in here if it
[14:36] was or wasn't invented under a
[14:38] government contract because then the
[14:40] government can use it free of
[14:42] charge and uh let's see here applicant
[14:47] and oh this is another important section
[14:49] small claim or Micro Entity small entity
[14:52] or Micro Entity status so if you are a
[14:56] small entity you will pay less than a
[14:58] large corporation for example and I mean
[15:01] large like 500 employees or more is a
[15:04] large
[15:05] corporation uh less than that you can
[15:07] pay a uh small entity status there's
[15:10] also uh limitations
[15:13] on um income and things like that
[15:16] especially for Micro Entity status so
[15:18] for Micro Entity status there's a few
[15:21] limitations here so let me go to
[15:27] them
[15:31] here we go micro enti status how can you
[15:35] establish it so you can just search
[15:37] USPTO Micro Entity and will come up and
[15:41] basically uh you can come down here to
[15:44] gross income basis and it's something
[15:46] like you earn less than three times the
[15:49] medium household income in the United
[15:52] States or if you are a student or
[15:55] working for a
[15:57] university uh and then also you don't
[15:59] have any more than
[16:01] four granted patents I
[16:05] think
[16:07] um States it somewhere in here you'd
[16:10] have to go read it again but they they
[16:12] basically are trying to incentivize
[16:16] people who want to do this to be able to
[16:22] afford it and you can actually sit that
[16:23] in the fee schedule you know a
[16:26] provisional application filing fee is
[16:28] $60 for Micro Entity $1 1220 for small
[16:32] and $300 regular fee and you compare
[16:36] that to a regular basic utility
[16:39] electronic filing
[16:41] fee
[16:43] um and you basically will see you know
[16:46] all these things are $300 or less and
[16:50] then you had have
[16:52] to um for a regular non-provisional
[16:55] utility pay for like your patent search
[16:58] for through the office for the patent
[17:00] office to actually search and look for
[17:02] other patents and then evaluation of
[17:04] your patent and all things like that but
[17:06] even still alln um it doesn't get crazy
[17:11] expensive until you start submitting DNA
[17:14] sequences of 800 megabytes or more then
[17:17] they start charging you it looks like
[17:20] $10,000
[17:21] uh so either way if you ever want to
[17:24] look at this this is USPTO fee schedule
[17:27] and now onto filing so filing is super
[17:31] straightforward so you're going to go to
[17:33] the USPTO you're going to go to patents
[17:36] you're going to go to filing
[17:38] online and then you're going to come
[17:40] down here and go to open EFS web
[17:44] unregistered now if you're going to file
[17:46] a lot of patents eventually you can get
[17:48] a registration number and that can make
[17:51] it easier for you to file patents and
[17:53] also keep track of where they are in the
[17:54] status of them which I would recommend
[17:57] if you're filing after your second or
[17:59] third one go just get yourself a
[18:02] uspto.gov
[18:04] account make note that it is kind of a
[18:07] pain to get it and they require a lot of
[18:11] uh credentials in terms of like send us
[18:14] this form verify your ID a whole bunch
[18:17] of other things but once you have it
[18:18] it's nice to have it so you open EFS web
[18:21] unregistered and it's going to pull up
[18:23] this site and I already had put in some
[18:25] fake Ino info here so Jojo Joe Jefferson
[18:30] and so you sign on as an unregistered
[18:34] Eiler new application
[18:37] utility provisional and you can see you
[18:40] can do uh design and you can ask for
[18:45] supplemental exams and all sorts of
[18:47] other things I'm not going to get into
[18:49] those so you're going to hit
[18:53] continue and then this is we're going to
[18:55] enter the title of the invention so I
[18:57] would enter in some title
[19:00] here and then we don't have an attorney
[19:02] docket number because we're not an
[19:04] attorney doing this uh application data
[19:07] sheet up top so with
[19:11] this you either have your own
[19:14] application data sheet which I will show
[19:16] you what
[19:18] mine looked like so so that
[19:21] certification Micro
[19:23] Entity provisional cover sheet I think I
[19:26] had another application data sheet
[19:27] somewhere but either way so you can
[19:31] either fill out all of it in the web-
[19:33] based one which you're going to add all
[19:35] of your name and info and all that or
[19:37] you can just do the application data PDF
[19:41] which is what I did
[19:43] before you do whichever one's easier for
[19:46] you and then you just write in here
[19:50] JoJo Jo Hanson if your name's JoJo
[19:54] Johanson by the way I'm sorry um and
[19:57] then so this is where if you do have a
[19:59] customer
[20:00] number uh You' enter it there or they
[20:03] just want an address and you just put in
[20:05] your address so like one two three fake
[20:09] Street uh oh that's name Jojo
[20:14] Jojo one two three fake
[20:18] streets uh
[20:23] Chicago Illinois United States none of
[20:27] that other info next I mean you'd want
[20:29] to enter it but I'm not going to okay
[20:32] great now we add our documents and this
[20:35] is where it'll yell at you if you have
[20:36] the wrong PDF or whatever so I like to
[20:39] do is go in and oh where did I put all
[20:45] this let me look for it here it
[20:50] is so we'll go
[20:53] into select anything you want so s sp1
[20:57] 15a hit
[20:59] okay and then you're going to choose
[21:01] what it is this is the entity status
[21:06] correspondence and this is a
[21:08] certification of Micro Entity gross
[21:10] income
[21:11] basis and then you
[21:15] go does our PDF contain multiple
[21:18] documents no so then you go add file get
[21:20] your next One S
[21:22] sp16 okay what is this uh this is the
[21:30] General transmittal we have to double
[21:33] check um here it is provisional cover
[21:36] sheet SP sp16 Tada so then again add
[21:39] file choose file next
[21:45] drawings so there's
[21:47] drawings General
[21:49] transmitt and you would
[21:55] find uh nope application part
[21:58] there we go drawings only black and
[22:01] white drawings or drawings other than
[22:03] black and white line drawings so since I
[22:05] have color in there I'd want to choose
[22:08] other and then I'm going to add another
[22:11] one choose
[22:13] file and then this is where I'd have the
[22:19] specification looks I do have a
[22:22] transmittal form in there so
[22:24] specification
[22:26] okay and then I come in here and I would
[22:30] choose
[22:31] specification and then add one last
[22:35] file and I'd
[22:40] say General transmitt transmitt of new
[22:44] application and I got to choose my
[22:46] transmittal
[22:48] form
[22:52] okay and then you go upload and
[22:56] validate so
[22:59] it's not going to upload and yell at me
[23:01] if any of these are
[23:06] incorrect so it is doing all of it it's
[23:09] probably going to yell at me that maybe
[23:10] none of this info here is correct which
[23:13] is
[23:14] possible um so so here we go sb16 this
[23:20] is not a USPTO supplied cover sheet
[23:23] form so you might want to remove that so
[23:26] in general though what you might want to
[23:28] do is I like to click on each one of
[23:31] these and open it up and see if it has
[23:34] all the info and if it does then you
[23:38] want to go through until you have no
[23:39] more errors and if you look this isn't
[23:43] um this isn't an error because it's not
[23:45] red it'll actually allow me to continue
[23:47] which I'll do just for the sake of
[23:49] moving this video along it's just a
[23:50] warning saying that this isn't correct
[23:53] so you just want to make sure you
[23:54] correct that item so you click through
[23:56] all of these corre correct them and then
[23:59] you go to the next section continue and
[24:01] this is where you want to calculate your
[24:03] fees so here I'm going to click on Micro
[24:07] Entity and it's a
[24:10] provisional and now it's saying
[24:13] $60 was this application originally
[24:16] filed on paper no number of
[24:20] pages
[24:24] um I don't know I think it's like five
[24:27] you can calculate however many pages you
[24:29] think it
[24:30] is
[24:32] um you don't even have to really enter
[24:34] that because it's not over the amount
[24:38] and then you just hit
[24:41] calculate and so it comes out to $60 is
[24:46] what we owe for our provisional Micro
[24:48] Entity and so you would go over here to
[24:53] continue and then you would look over
[24:56] everything here here and I'm going to
[24:59] just make this wide and when you're done
[25:01] you would click submit and then after
[25:04] that you come up and you would pay your
[25:08] fee um which is yelling at me it hasn't
[25:11] been submitted so I can't but you pay a
[25:13] fee so it submits it and then asks you
[25:16] to pay you can actually submit it and
[25:18] then not pay uh which I won't get into
[25:21] right now but in theory you can do that
[25:24] but then they can actually come after
[25:26] you and try and get a whole bunch of um
[25:30] late fees and whatnot with that
[25:32] potentially and then you get a receipt
[25:35] and the receipt will basically give you
[25:37] tracking on this so that if you ever
[25:39] want to look it up and specifically if
[25:41] you want
[25:43] to uh later on include it with your
[25:47] non-provisional patent application
[25:49] stating that it has priority over your
[25:53] non-provisional application meaning it
[25:55] is your stake in the sand
[25:59] then you'd want that information so that
[26:04] is basically all I have for filing your
[26:08] provisional patent application it's not
[26:10] that hard it really can take you know an
[26:14] hour from making the drawings up and
[26:17] writing your specs and submitting it and
[26:21] $60 so when somebody says Hey I want to
[26:25] charge you $3,000 to write up a
[26:27] provision application which is what
[26:29] happened to me on one of my first
[26:31] projects then uh just realize that you
[26:35] probably can save yourself that $33,000
[26:38] and do it
[26:39] yourself so I'm going to do another
[26:43] video on kind
[26:46] of I guess trying to sell your idea a
[26:50] bit more once you've got your
[26:51] provisional um but the big thing
[26:53] actually now is you have your
[26:55] provisional patent application so so you
[26:57] should be able to take that knowing that
[26:59] your idea is protected and start trying
[27:02] to sell your idea try and get funding
[27:07] without any fear of anybody taking it
[27:09] because you've got a one-year clock
[27:12] before you have to file a more expensive
[27:15] utility non-provisional
[27:17] application and so this is your time to
[27:21] really prove out whether or not your
[27:22] idea has you know can pass muster and if
[27:27] it can
[27:28] then great you know then you probably
[27:30] can move forward on that project but if
[27:32] it doesn't then you only spent $60 and
[27:35] all your time and you can do another
[27:38] thing so I hope this was interesting if
[27:41] you like what you saw please like And
[27:44] subscribe and I will keep providing more
[27:46] of this content
[27:48] thanks
