Prior art search and drafting services are primarily provided by registered patent attorneys, patent agents, specialized intellectual property (IP) law firms, and dedicated patent search agencies.
Because the United States Patent and Trademark Office (USPTO) uses advanced AI-assisted search tools that make it easier for examiners to find similar inventions, securing professional help is highly recommended to ensure your application stands out.
Here is a breakdown of who offers these services and how to choose the right partner:
These individuals are licensed by the USPTO to represent inventors. They can perform searches, provide legal opinions on patentability, and legally draft and file your application.
IP boutique firms or IP departments within larger law firms provide end-to-end services. They handle everything from early-stage prior art screening to commercialization strategies.
If you want to save money on the search phase before hiring an attorney to write the application, you can hire a dedicated search firm.
Before paying a professional, you should always do a preliminary search yourself to see if your idea already exists publicly.
Key Summary of Service Types
| Provider Type | Offers Prior Art Search? | Offers Legal Patent Drafting? | Best Used For |
|---|---|---|---|
| Patent Attorney | Yes | Yes | Complete legal protection and enforcement strategy |
| Patent Agent | Yes | Yes | Technically complex drafting at a slightly lower rate |
| Search Firm | Yes | No (Technical only) | Budget-friendly, deep-dive global data sweeps |
| Self-Search | Yes (Basic) | No | Initial idea filtering before spending money |
To help me point you in the right direction, what industry or technology field does your invention fall under (e.g., software, medical device, mechanical)? Also, do you have a specific budget in mind for filing?
Yes. If you’re preparing a **U.S. patent application**, there are several types of providers that can handle both **prior-art searching** and **patent drafting**. I’d generally favor a **USPTO-registered patent attorney or patent agent** who can carry the project from search → claim strategy → drafting → filing,…
Yes. If you’re preparing a U.S. patent application, there are several types of providers that can handle both prior-art searching and patent drafting. I’d generally favor a USPTO-registered patent attorney or patent agent who can carry the project from search → claim strategy → drafting → filing, rather than using a standalone search company.
The USPTO itself recommends considering a patent attorney or agent for both prior-art searching and application preparation.
Before hiring anyone, ask these five questions:
Also, don't confuse a patentability/prior-art search with a freedom-to-operate (FTO) search. A patentability search asks, essentially, “Can I potentially obtain a patent?” FTO asks “Can I make/use/sell this without infringing someone else's patent?” They are different analyses.
You can independently verify that an attorney or agent is registered with the USPTO using its oedci.uspto.gov.
If you tell me what your invention is (even at a high level), your budget, and whether you're looking for a provisional or non-provisional application, I can narrow this to 3–5 providers that are particularly suitable for your technology and compare their published pricing/services.
When preparing to file a patent, you can source prior art search and drafting services from a few different categories of providers, depending on your budget, complexity of the invention, and desired level of legal…
When preparing to file a patent, you can source prior art search and drafting services from a few different categories of providers, depending on your budget, complexity of the invention, and desired level of legal protection.
The primary options available in the market include:
If you'd like to narrow this down, please let me know:
- **RatnerPrestia** - 1007 Orange St Ste 205, Wilmington, DE 19801, United States - **Keeley-DeAngelo Intellectual Property** - 1105 Tree St, Philadelphia, PA 19148 - **PatentXL Law Firm** - Two Bala Plaza, Bala Cynwyd, PA 19004, United States
Yes. Since you’re in the Delaware/Philadelphia area, there are several providers that specifically advertise both prior-art searching and patent application drafting/prosecution.
I'd generally recommend not treating the prior-art search and drafting as completely separate jobs if you're preparing to file. A good patent practitioner can use the search results to shape the claims and specification around the relevant prior art.
A useful process is:
For example, DP IP Group explicitly describes using prior-art searching to identify ways of distinguishing the invention and positioning it for stronger claims, rather than merely handing the inventor a list of search results.
Ask whether you're getting a "patentability search" or merely a patent search report. The former should involve someone who can interpret the references in light of U.S. patentability requirements. If you want an actual legal patentability opinion, have a USPTO-registered patent attorney provide it.
You can also independently verify that the person you hire is registered to practice before the USPTO using its practitioner database.
If you tell me what your invention does/what industry it's in (you don't need to reveal confidential implementation details), I can narrow this down to 5–7 firms that are particularly well suited to your technology, and compare their likely strengths, location, and pricing model.
Yes. I found several U.S.-focused providers that offer **prior-art/patentability searches and patent application drafting**, ranging from patent law firms to specialist search firms. ### Firms worth comparing | Provider | Prior-art search | Drafting | Published pricing / positioning |
Yes. I found several U.S.-focused providers that offer prior-art/patentability searches and patent application drafting, ranging from patent law firms to specialist search firms.
| Provider | Prior-art search | Drafting | Published pricing / positioning |
|---|---|---|---|
| Underwood & Associates | Yes | Yes | Patentability search listed at $1,200 flat rate; also drafts/prosecutes U.S. and international applications. underwoodpatents.com |
| GTC | Yes | Yes | Search from $400–$500 depending on jurisdiction/service; U.S. drafting & filing from $2,700. Uses registered patent counsel. globaltrademarkcompany.com |
| Cann IP | Yes | Yes | Prior-art search listed at $1,275; utility application drafting starts around $5,600. www.canniplaw.com |
| Vertex IP | Yes | Yes | U.S. patentability search roughly $1,200–$1,400; worldwide $1,500–$2,000; nonprovisional utility drafting roughly $4,500–$5,500 for a representative 20-claim application. vertex-ip.com |
| Elevate Patent Group | Yes | Yes | End-to-end search, patentability analysis, drafting and USPTO filing, handled by a registered patent agent. vertex-ip.comelevatepatentgroup.com |
| ZYL Law Firm | Yes | Yes | Combines professional database searching with public-disclosure research and provides drafting-oriented analysis rather than merely a list of references. zyllaw.com |
| Aegis Patent Services | Yes | No/primarily search | Independent prior-art research for inventors, businesses and law firms; says searches are performed in the U.S. and not outsourced. aegispatentservices.com |
| Parola Analytics | Yes | Yes | Offers patentability searches, opinions through a partner U.S. IP firm, drafting, filing and prosecution. parolaanalytics.com |
If you're actually preparing to file, I'd favor a registered patent attorney or patent agent who can both interpret the prior art and draft the application, rather than buying a cheap automated search and then handing the results to somebody else.
The important distinction is that a good search isn't simply "here are 30 patents that mention similar words." You want someone to:
For example, ZYL specifically describes its service as producing drafting direction and fallback levels rather than just a raw hit list. zyllaw.com Aegis, by contrast, is more appropriate if you want an independent search specialist and already have an attorney/drafter.
A patentability/prior-art search is not the same thing as a freedom-to-operate (FTO) search. If your concern is "Can I get a patent?", you want patentability analysis. If your concern is "Can I sell this product without infringing somebody else's active patent?", that's a different analysis.
If you tell me (1) what your invention is generally about, (2) whether you're looking for a provisional or non-provisional U.S. patent, and (3) your approximate budget, I can search specifically for 5–10 reputable providers that fit your situation and compare their current prices, credentials, and reviews.

Yes. If you’re preparing a U.S. patent filing, you have several types of providers to choose from. The important distinction is whether you want just a prior-art search or a provider who can take the results and develop a patentability/claim strategy and draft the application.
For an important invention, I would not treat a generic "patent search company" and a patent attorney/agent as interchangeable.
A good workflow is:
The USPTO itself recommends considering a patent attorney or agent for both searching and drafting, and provides a searchable roster of practitioners.
One caution: I'd be especially wary of anyone promising that a search can establish that your invention is "patentable." A search can reduce uncertainty; it cannot guarantee that the USPTO will grant a patent. The quality of the claim analysis and drafting is often more consequential than simply receiving a long list of patent references.
If you tell me (1) what your invention does in 2–5 sentences, (2) whether you're looking for a provisional or non-provisional, and (3) roughly what you'd like to spend, I can narrow this to the 3–5 best-fit providers and compare their likely costs, strengths, and tradeoffs.
Yes. For a U.S. patent, you have several options, ranging from independent prior-art researchers to patent law firms that handle the **search → patentability assessment → drafting → filing → prosecution** process. ### Providers worth considering - **[ZYL Law](https://zyllaw.com/patent.php?utm_source=chatgpt.com)** —…
Yes. For a U.S. patent, you have several options, ranging from independent prior-art researchers to patent law firms that handle the search → patentability assessment → drafting → filing → prosecution process.
There are also many conventional patent firms that can do both jobs. The USPTO maintains an official directory of registered patent attorneys and patent agents, and you can filter it by location and whether the practitioner is accepting new clients.
If you're preparing to file, I would generally not treat the prior-art search and drafting as completely separate commodities. The search should influence how the claims are structured. A good workflow is:
The USPTO specifically notes that a prior-art search before filing isn't mandatory but is advisable, and recommends using a registered patent attorney or agent for preparing and prosecuting an application.
One important distinction: a patent agent can prepare and prosecute patent applications before the USPTO, just like a patent attorney, but generally cannot perform legal services outside that USPTO practice (such as certain contracts or litigation).
If you tell me (1) what your invention does at a high level, (2) whether it's software/AI, mechanical, electronics, biotech, etc., and (3) whether you're looking for a U.S. filing only or eventually international protection, I can narrow this down to 5–10 firms/providers that are particularly appropriate, including typical pricing and what to ask them before hiring them.

When preparing to file a patent, getting a thorough prior art search (patentability search) and a professionally drafted application are critical steps.
